Abstract
CONTEXT.— Syphilis, a reemerging disease caused by the spirochete Treponema pallidum, is becoming more frequent in surgical pathology and hematopathology practices. Hematopathologists typically receive lymph node biopsies from patients with syphilis who have localized or diffuse lymphadenopathy. Occasionally, syphilis infection in the aerodigestive tract can show a prominent lymphoplasmacytic infiltrate and mimic lymphoma. Besides the varying and occasional atypical morphology, the fact that clinical suspicion tends to be low or absent when histologic evaluation is requested adds to the importance of making this diagnosis. OBJECTIVE.— To summarize histologic features of syphilitic lymphadenitis and syphilis lesions in the aerodigestive tract, and to review differential diagnosis and potential diagnostic pitfalls. DATA SOURCES.— Literature review via PubMed search. CONCLUSIONS.— Characteristic histologic findings in syphilitic lymphadenitis include thickened capsule with plasma cell-rich inflammatory infiltrate, reactive follicular and paracortical hyperplasia with prominent lymphoplasmacytic infiltrate, and vasculitis. Lymph nodes, however, can show a number of other nonspecific histologic features, which frequently makes the diagnosis quite challenging. In the aerodigestive tract, syphilis is characterized by plasma cell-rich infiltrates. Immunohistochemistry for T pallidum is the preferred method for detecting spirochetes; however, this immunohistochemical stain shows cross-reactivity with other treponemal and commensal spirochetes. Differential diagnosis of syphilis in lymph nodes and the aerodigestive tract is broad and includes reactive, infectious, and neoplastic entities. Pathologists should be aware of the histologic features of syphilis and keep this challenging entity in the differential diagnosis.

Hutchings DA, Larson BK, Guindi M, Waters KM. Markedly increased duodenal villous surface apoptosis in patients taking pre-exposure prophylaxis (PrEP) against human immunodeficiency virus. Histopathology 2024; 84:888-892. [PMID: 38192211 DOI: 10.1111/his.15137] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 12/13/2023] [Accepted: 12/20/2023] [Indexed: 01/10/2024]
Abstract
AIMS Pre-exposure prophylaxis (PrEP) consists of combination antiretroviral therapy and is increasingly utilized to prevent human immunodeficiency virus (HIV) in high-risk populations. Two index cases noted during routine care showed markedly increased duodenal villous surface apoptosis in patients on PrEP. We sought to examine the prevalence of this finding and identify any clinicopathologic correlations. METHODS Gastrointestinal biopsy specimens from 23 male patients aged 18-40 years taking PrEP and 23 control patients were reviewed. Patients with HIV, inflammatory gastrointestinal diseases, and celiac disease were excluded. Apoptoses were counted on surface epithelium and deep crypts. The highest apoptotic body count per tissue fragment was recorded. Clusters were defined as groups of ≥5 apoptoses. Apoptotic counts between patients taking PrEP and controls were compared using t-tests. RESULTS In PrEP patients, the median age was 35 years (range 25-40) and 83% (19/23) were white. The control patients were demographically similar (median age: 32 years [range 23-40]; 70% [16/23] white). Duodenal apoptosis in villous surface epithelium was increased in PrEP patients, with 14/23 (60.9%) patients having ≥10 surface apoptoses compared to 2/23 (8.7%) controls (P = 2.1 × 10-3 ) and 14/23 (61%) having clusters compared to 3/23 (13%) controls (P = 2.0 × 10-3 ). There was no significant association between increased surface apoptosis or clusters and clinical symptoms or duration of PrEP use. CONCLUSION Markedly increased villous surface apoptosis, particularly in clusters, is often seen in the duodenum of patients taking PrEP. Although the mechanism and significance are unknown, knowledge of this peculiar finding may prevent unnecessary additional testing.

Abstract
Infectious diseases of the GI tract mimic a variety of other GI diseases, including chronic idiopathic inflammatory bowel disease and ischemia. It can be challenging to identify pathogens in tissue sections as well, as many trainees are not exposed to infectious disease pathology other than in the context of microbiology. Our ability to diagnose infections in formalin fixed, paraffin embedded material has grown exponentially with the advent of new histochemical and immunohistochemical stains, as well as more options for molecular testing. Correlating these diagnostic techniques with morphology has led to increasing understanding of the histologic patterns that are associated with specific pathogens.

Abstract
Distinguishing inflammatory bowel disease (IBD) from its mimics remains a diagnostic challenge for surgical pathologists. Several gastrointestinal infections produce inflammatory patterns that overlap with typical findings of IBD. Although stool culture, PCR, and other clinical assays may identify infectious enterocolitides, these tests may not be performed or the results may be unavailable at the time of histologic evaluation. Furthermore, some clinical tests, including stool PCR, may reflect past exposure rather than ongoing infection. It is important for surgical pathologists to be knowledgeable about infections that simulate IBD in order to generate an accurate differential diagnosis, perform appropriate ancillary studies, and prompt clinical follow-up. This review covers bacterial, fungal, and protozoal infections in the differential diagnosis of IBD.

Abstract
Background. The aim of our study was to describe 50 cases of inflammatory bowel disease (IBD) and HIV co-existence that are under medical supervision in Warsaw. Methods. This was a retrospective descriptive study. Fifty HIV-infected patients, diagnosed with IBD during the years 2001–2019, were identified. IBD was diagnosed endoscopically and then confirmed by biopsy. All data was obtained from medical records. Results. All studied patients were male with a median age of 33 years old (range 20–58 years). All, except one, were men who have sex with men (MSM). The median CD4 cell count was 482 cells/µL (range 165–1073 cells/µL). Crohn’s disease (CD) was diagnosed in 7 patients (14%), ulcerative colitis (UC) in 41 patients (82%), and 2 patients (4%) had indeterminate colitis. Forty-nine patients (98%) reported a history of unprotected receptive anal intercourse and different sexual transmitted infections (STIs). Only in 10 patients (20%) were one or more IBD relapses observed. Conclusions. We recommend HIV testing for every MSM with IBD suspicion. Moreover, STIs testing should be performed in every IBD patient with colorectal inflammation, using molecular and serological methods. Persons who reported unprotected receptive anal intercourse seem to have the biggest risk of STI-associated proctitis or proctocolitis mimicking IBD.

Abstract
OBJECTIVES Neisseria gonorrhoeae infection of the anorectal tract is often asymptomatic and infrequently biopsied, but pathologists can be tasked with identifying the histologic features of possible infection. The study was undertaken to better characterize clinical and morphologic features of confirmed anorectal gonococcal infection. METHODS From 2011 to 2020, 201 positive gonococcal nucleic acid amplification testing samples from 174 patients collected from the distal colorectum and/or anus were matched to eight patients with concurrent biopsy specimens of the distal anorectum. Complete demographic, clinical, and infectious information was collected for each biopsied patient. The histomorphologic features of each biopsy were systematically tabulated. RESULTS All eight gonococcal cases were obtained from men who have sex with men. Each case showed at least mild acute inflammation with moderate activity identified in one case with concurrent cytomegalovirus infection. Intense lymphoplasmacytic infiltration was not commonly seen (two of eight). Half of the cases showed mucosal ulceration, and seven of eight cases demonstrated lymphoid aggregates. CONCLUSIONS The microscopic features are mild compared with other well-described types of infectious proctitis, with most cases displaying mild acute inflammation and scattered lymphoid aggregates. These findings highlight the importance of obtaining a complete patient history and recommending additional infectious workup even when only subtle changes are present.

Abstract
Introduction Since 2003, a progressive increase in sexually transmitted infections (STI), presented as proctitis, has been described in homosexual men. In 2013 Arnold et al. described microscopic features that enable pathologists to formulate a histological diagnosis of STI related proctitis. The aim of this study is to identify the presence of Chlamydia trachomatis by immunohistochemistry in a group of patients with male to male sexual activity and pathology compatible with STI proctitis. Methods Cross-sectional study. The study included 54 patients with risky sexual activity and histopathology compatible with STI-proctitis according to Arnold´s recommendations. The Chlamydia trachomatis identification was carried out retrospectively on paraffin blocks using mouse monoclonal antibodies from Santa Cruz biotechnology.
Results all patients were young men with male to male sexual activity, 69% were positive for HIV. The most common endoscopic presentation was rectal ulcer (61%). Basal lymphoplasmacytic inflammation and mild crypt distortion were the most common histological findings. The immunohistochemical study identified positivity for Chlamydia trachomatis in 40% (18 of 45 tested) of STI proctitis cases. Discussion The epidemiological and endoscopic characteristics of the patients studied are similar to those previously reported. In accordance with Arnold et al., the most common histological findings were (a) mild distortion of the crypts; (b) dense and basal lymphoplasmacytic infiltrate and (c) scarcity of eosinophils. The positivity of chlamydia trachomatis in immunohistochemistry was lower than others studies that used PCR for this purpose. We did not find similar published studies to compare our results. Conclusions In summary, 54 cases of patients with STI related proctitis are presented, all of them with distinctive histological characteristics and third of the cases tested positive by IHC for Chlamydia trachomatis. Supplementary Information The online version contains supplementary material available at 10.1186/s12876-022-02233-w.

Abstract
BACKGROUND Several lymphogranuloma venereum (LGV) outbreaks among men who have sex with men (MSM) have been reported throughout the world since 2003. Nevertheless, no LGV cases have been internationally reported from Russia. We evaluated the prevalence of LGV among MSM attending proctologists in Moscow, Russia, and compared the LGV and non-LGV rectal Chlamydia trachomatis (CT) infections. METHODS MSM (n = 534) attending for proctologic care were included. Rectal specimens were sampled for CT and Neisseria gonorrhoeae (NG) by nucleic acid amplification tests (NAATs). All CT-positive patients were tested with an LGV-specific NAAT. RESULTS In total, 37.3% (95% CI 33.3-41.5; 199/534) of MSM were CT positive. Of these, 68.8% (95% CI 62.1-74.9; 137/199) had LGV and 31.2% (95% CI 25.1-37.9; 62/199) a non-LGV rectal CT infection. Older age (34 years vs. 31 years, p = 0.035) and group-sex practices (67.2% (92/137) vs. 33.9% (21/62), p < 0.0001) were associated with LGV. The LGV-positive MSM were also more likely to be HIV-positive (67.2% (92/137) vs. 41.9% (26/62), p = 0.001). Proctoscopy revealed ulcerative proctitis/proctocolitis in 99.3% (136/137) of LGV-positive MSM. No ulcerative or erosive proctitis was found in the MSM with non-LGV CT infection, but 58.1% (36/62) of them had anorectal disorders. Finally, mild catarrhal or hemorrhagic proctitis was diagnosed in only 21.6% (8/37) of MSM with non-LGV CT infection lacking concomitant NG or syphilis (p < 0.0001). CONCLUSIONS LGV is widely spread among MSM attending proctologists in Moscow. Clinically, acute LGV proctitis/proctocolitis can be difficult to distinguish from inflammatory bowel disease that leads to mismanaged LGV infections. LGV diagnostic laboratory testing is essential, however, currently mainly lacking for MSM in Russia. All MSM with CT-positive rectal specimens should be subsequently tested for LGV.

Abstract
INTRODUCTION Many diseases can imitate inflammatory bowel disease [IBD] clinically and pathologically. This review outlines the differential diagnosis of IBD and discusses morphological pointers and ancillary techniques that assist with the distinction between IBD and its mimics. METHODS European Crohn's and Colitis Organisation [ECCO] Topical Reviews are the result of an expert consensus. For this review, ECCO announced an open call to its members and formed three working groups [WGs] to study clinical aspects, pathological considerations, and the value of ancillary techniques. All WGs performed a systematic literature search. RESULTS Each WG produced a draft text and drew up provisional Current Practice Position [CPP] statements that highlighted the most important conclusions. Discussions and a preliminary voting round took place, with subsequent revision of CPP statements and text and a further meeting to agree on final statements. CONCLUSIONS Clinicians and pathologists encounter a wide variety of mimics of IBD, including infection, drug-induced disease, vascular disorders, diverticular disease, diversion proctocolitis, radiation damage, and immune disorders. Reliable distinction requires a multidisciplinary approach.

Abstract
This review, based on the content of the 2020 US Gastrointestinal Pathology Society's Rodger Haggitt Lecture, concerns an array of tubular gastrointestinal tract dysplastic or possible "predysplastic lesions" with an almost purely morphologic focus based on our collaborative efforts over the past few years. These processes include esophageal epidermoid metaplasia, Barrett esophagus-associated dysplasia, polypoid gastric dysplastic lesions, small intestinal dysplasia, and the ability of metastases to mimic it, the controversial "serrated epithelial change" encountered in the setting of long-standing ulcerative and Crohn colitis, and recently described anal columnar human papilloma virus-associated neoplasms.

Abstract
Background Syphilis infections are increasing globally. Lower gastrointestinal syphilis (LGIS) is a
rare manifestation of early syphilis transmitted through anal sexual contact. Misdiagnosis of
LGIS as inflammatory bowel disease may result from clinician underawareness. Methods We searched the literature for articles describing cases of LGIS, and identified additional
cases diagnosed within our institution. Data were extracted from the articles and medical
records and analyzed to provide a summative account. Results Fifty-four cases of LGIS were identified in 39 articles published between 1958 and 2020.
Eight additional cases were diagnosed at our institution between 2011 and 2020, totaling 62
cases. All cases were described in men and transwomen aged 15–73 years. Fifty (93%)
individuals reported having sex with men. In 26 cases (52%), the individuals were human
immunodeficiency virus (HIV) coinfected. LGIS presented most commonly with hematochezia (67%)
and anal pain (46%). The most common physical examination findings were rectal mass (38%),
lymphadenopathy (31%), and rash (26%). Nontreponemal titers ranged from 1:2 to 1:1024. Of the
52 cases in which endoscopy was reported, 22 (42%) showed anorectal mass and 18 (35%) showed
anorectal ulcer. In 44 cases (75%), histopathology revealed a chronic inflammatory infiltrate
with a prominent lymphocyte component (45%) and/or plasma cells (36%). Seventy-eight percent
of specimens to which a tissue stain was applied were positive for spirochetes. Conclusions LGIS should be suspected in men and transwomen presenting with a lower gastrointestinal
symptom or mucosal abnormality. A sexual history must be elicited and guide testing.
Misdiagnosis can delay treatment and threatens patient and public health.

J Eur Acad Dermatol Venereol 2021; 35:1434-1443. [PMID: 34057249 DOI: 10.1111/jdv.17269] [Citation(s) in RCA: 32] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Accepted: 03/24/2021] [Indexed: 12/14/2022]
Abstract
This guideline intents to offer guidance on the diagnosis and management of patients with gastrointestinal symptoms and a suspected sexually transmitted cause. Proctitis is defined as an inflammatory syndrome of the anal canal and/or the rectum. Infectious proctitis can be sexually transmitted via genital-anal mucosal contact, but some also via digital contact and toys. Neisseria gonorrhoeae, Chlamydia trachomatis (including lymphogranuloma venereum), Treponema pallidum and herpes simplex virus are the most common sexually transmitted anorectal pathogens. Shigellosis can be transferred via oral-anal contact and may lead to proctocolitis or enteritis. Although most studies on these infections have concentrated on men who have sex with men (MSM), women having anal intercourse may also be at risk. A presumptive clinical diagnosis of proctitis can be made when there are symptoms and signs, and a definitive diagnosis when the results of laboratory tests are available. The symptoms of proctitis include anorectal itching, pain, tenesmus, bleeding, constipation and discharge in and around the anal canal. The majority of rectal chlamydia and gonococcal infections are asymptomatic and can only be detected by laboratory tests. Therefore, especially when there is a history of receptive anal contact, exclusion of anorectal infections is generally indicated as part of standard screening for sexually transmitted infections (STIs). Condom use does not guarantee protection from STIs, which are often spread without penile penetration. New in this updated guideline is: (i) lymphogranuloma venereum proctitis is increasingly found in HIV-negative MSM, (ii) anorectal Mycoplasma genitalium infection should be considered in patients with symptomatic proctitis after exclusion of other common causations such N. gonorrhoeae, C. trachomatis, syphilis and herpes, (iii) intestinal spirochetosis incidentally found in colonic biopsies should not be confused with syphilis, and (iv) traumatic causes of proctitis should be considered in sexually active patients.

Abstract
AIMS Recent studies from multiple global regions have reported a resurgence of lymphogranuloma venereum (LGV) proctitis, which is caused by Chlamydia trachomatis (CT). LGV proctitis is histologically indistinguishable from other forms of sexually transmitted proctitis and is difficult to differentiate from inflammatory bowel disease. While immunohistochemical stains are available for syphilis, there is no commonly available stain for the tissue identification of CT. MATERIALS AND METHODS From 200 positive CT nucleic acid tests (NAT) from anorectal swabs, we identified 12 patients with biopsies collected from the distal colorectum or anus within 90 days of the positive NAT. We collected basic demographic information and tabulated clinical and histological findings. We examined the performance of a novel RNA in-situ hybridisation (ISH) stain targeting CT 23s rRNA on these 12 cases and 10 controls from the anorectum. RESULTS All 12 patients were male; nine were HIV+, two had concurrent gonococcal infection, one had concurrent syphilis and one had cytomegalovirus co-infection. The majority of biopsies (11 of 12) showed mild or moderate acute inflammation, had a prominent lymphoplasmacytic infiltrate (eight of 11) and lacked marked crypt distortion (10 of 10). The RNA ISH stain was positive in 10 of 12 cases (sensitivity 83%). One case showed equivocal staining. No controls showed definitive positive staining (specificity 100%). One had equivocal staining. CONCLUSION Our series showed that anorectal LGV had similar histological findings to those of prior STI proctitis series predominantly comprised of syphilis. The novel RNA ISH stain was sensitive and specific and may show utility in differentiating types of STI proctitis.

Abstract
This review article discusses the challenges of making a firm histopathological diagnosis of inflammatory bowel disease (IBD) on biopsy and resection material and the importance of its distinction from a range of other inflammatory and infective conditions that may closely mimic IBD. In many cases, the diagnosis of ulcerative colitis or Crohn's disease is straightforward, especially when patients have a typical presentation and characteristic histopathological features. Knowledge of the full clinical history is very important, particularly past and recent medical history, drug history, foreign travel, or known contact with individuals with specific infection. Discussion of all cases of suspected IBD within a multidisciplinary team meeting is required to ensure that clinical, radiological, and pathological features can be correlated. Mimics of IBD can be divided into 4 categories: 1) those due to specific infection, 2) those due to a specific localized inflammatory process, 3) those due to iatrogenic causes, and 4) other rarer causes. Accurate diagnosis of IBD and exclusion of these mimics are crucial for patient management. Once a diagnosis of IBD has been proffered by a pathologist, it is very difficult to "undiagnose" the condition when an alternative diagnosis or "mimic" has been subsequently identified. The histological diagnosis of each of these IBD mimics is discussed in detail, with guidance on how to avoid the pitfall of missing these sometimes very subtle and "difficult to diagnose" conditions.

Abstract
Proctitis is an inflammation involving the anus and the distal part of the rectum, frequently diagnosed in the context of inflammatory bowel diseases (IBD). Nevertheless, when the standard therapy for IBD is ineffective, it becomes necessary for the clinician to review alternative etiologies, beginning from the broad chapter of infectious causes up to rare causes such as radiation, ischemia, diversion and traumatisms. While it is possible to find infectious proctitides caused by pathogens generally inducing extensive colitis, the growing incidence of both sexually transmitted infections and isolated proctitis reported in the recent years require a lot of attention. The risk appears to be higher in individuals participating in anal intercourse, especially men having sex with men (MSM) or subjects who use sex toys and participate to sex parties, dark rooms and so on. The commonest implicated pathogens are Neysseria gonorrhoeae, Chlamydia trachomatis, Herpes Simplex virus and Treponema pallidum. Herpes and Chlamydia infections mainly occur in HIV-positive MSM patients. Since symptoms and signs are common independently from etiology, performing a differential diagnosis based on clinical manifestations is complicated. Therefore, the diagnosis is supported by the combination of clinical history and physical examination and, secondly, by endoscopic, serologic and microbiologic findings. Particular emphasis should be given to simultaneous infections by multiple organisms. The involvement of experts in infectious diseases and in sexual health is crucial for the diagnostic and therapeutic management. The available therapies, empirically initiated or specific, in many cases are able to guarantee a good prognosis and to prevent relapses.

Abstract
AIM To assess the incidence of colonic spirochetosis, diagnosed by immunohistochemical stain with anti-Treponema pallidum antibody, in a prospective study of colonic biopsies of patients presenting with chronic diarrhea. MATERIAL AND METHODS From March 2017 to March 2018 the colonic biopsies of patients presenting with chronic diarrhea were stained with Hematoxylin Eosin and anti-Treponema pallidum antibody. The positive cases were also stained with Steiner stain. RESULTS A total of 137 colonic biopsies were assessed and 3 cases were positive for immunohistochemical stain with anti-Treponema pallidum antibody (2% of the patients). One case was easy to diagnose with HE stain but the 2 other cases were not. The bacteria were stained with Steiner stain, but less easily seen than with the immunohistochemical stain. No patient was treated with antibiotics. DISCUSSION AND CONCLUSION The colonic spirochetosis can be easily diagnosed by pathologists with immunohistochemical stain with anti-Treponema pallidum antibody. The bacteria are more easily diagnosed with immunohistochemical stain than with HE stain or Steiner stain. However, colonic spirochetosis is rarely diagnosed on colonic biopsies of patients presenting with chronic diarrhea (2% of the patients in our study). Due to the rarity of the entity, and the cost of immunohistochemical stain and the weak benefit for the patient (no patient in our study was treated with antibiotics for colonic spirochetosis) we cannot advise to perform systematic immunohistochemical stain with anti-Treponema pallidum antibody in all the colonic biopsies of patients presenting with chronic diarrhea.

Abstract
Syphilis, a sexually transmitted infection caused by the Gram-negative bacterium Treponema pallidum, is increasing in prevalence in the United States. It has been our experience that primary and secondary syphilis of the aerodigestive tract can afflict a large age spectrum with varied clinical and histopathologic findings, which can lead to diagnostic problems and frequent misdiagnosis. In this study, we describe the histopathologic patterns of syphilis of the aerodigestive tract to expand awareness of its varied appearance. We identify 3 patterns of inflammatory response to syphilis: plasma cell-rich, lymphohistiocytic, and lymphoma-like. We also report the presence of immunoglobulin G4-predominant plasma cells in the inflammatory response as a potential mimicker of immunoglobulin G4-related disease. Lastly, we found that use of T. pallidum immunohistochemical stain is more reliable than Steiner silver stain at the identification of spirochetes. Our study highlights that despite convention, plasma cells are not always abundant in syphilis. Awareness of the histopathologic range of syphilis in the aerodigestive tract by the surgical pathologist can lead to the correct diagnosis and guide appropriate treatment.

Abstract
OBJECTIVE Sexually transmitted diseases (STDs), mainly lymphogranuloma venereum (LGV), induce colorectal symptoms that may be misdiagnosed as inflammatory bowel disease (IBD). This study describes patients who presented with STDs masquerading as IBD in order to improve understanding of missed diagnosis of colorectal STDs and their association with LGV in Israel. METHODS This retrospective, descriptive study characterized the clinical, endoscopic, and pathological findings of 16 patients who were diagnosed with a colorectal STD after erroneously being diagnosed with IBD. Molecular genotyping was used to characterize some of the Chlamydia trachomatis isolates. RESULTS All patients were men who have sex with men (MSM), mostly HIV-1-positive, and had clinical and endoscopic findings compatible with IBD. The STD was diagnosed 1-36 months after the initial diagnosis: 14 were positive for Chlamydia trachomatis, of which three were of the LGV2b (ST58) serotype and one was ST 108 serotype. Five were positive for gonorrhea and four were positive for syphilis. Several pathogens were diagnosed in six episodes. CONCLUSIONS Colorectal STDs may resemble IBD and therefore their diagnosis may be delayed. IBD symptoms in MSM who engage in non-protected anal sex should prompt at least syphilis and anal PCR for STD testing. If C. trachomatis is diagnosed but LGV subtyping cannot be done, doxycycline 100mg twice daily for 21days should be recommended.

Abstract
BACKGROUND Human intestinal spirochetosis (IS) has been recognized for decades, but whether it represents commensalism or a pathogenic process remains controversial. IS is diagnosed on routine stains with confirmation by silver stains but these stains are labor intensive and slow to read. We evaluated the Treponema pallidum immunostain as a diagnostic adjunct for IS. METHODS We retrieved biopsies from 33 patients with IS for this study. Each case was tested by Warthin-Starry (WS) and T. pallidum immunohistochemistry (IHC). Species specific genotyping was performed in 3 cases. RESULTS Patients with IS ranged from 22 to 82 years without gender predilection. IS involved normal (n = 15), and inflamed (n = 5) mucosa and colonic polyps (n = 13). Warthin-Starry and T. pallidum IHC were positive in all cases including both species of Brachyspira. Six (18%) symptomatic patients were treated for IS, and experienced resolution. In patients diagnosed with incidental IS on cancer screening (n = 5), follow up biopsies, without therapy, were negative for IS. T. pallidum IHC required 75 min less hands-on time than WS for performance and was faster to interpret. CONCLUSIONS T. pallidum IHC can be used to confirm the diagnosis of IS and is easier to perform and faster to interpret than WS.

Abstract
The World Health Organization estimates that there is greater than one million new cases of sexually transmitted infections (STIs) every day. In many countries, STIs are at an unprecedented high, including the USA, where nearly 20 million new cases were reported in 2016. Although morbidity associated with STIs is usually seen in the context of genitourinary disease, these pathogens may also affect the gastrointestinal tract and cause anal pain, abdominal pain, or diarrhea. It is important to recognize patterns of injury associated with these pathogens, especially those that may mimic other gastrointestinal diseases, such as idiopathic inflammatory bowel disease (IBD). This review focuses upon STIs of the lower gastrointestinal tract, organized by the most common site of involvement: the anus, rectum, and colon.

Abstract
Histopathological assessment of biopsy and resection specimens of chronic inflammatory bowel disease (CIBD), or possible CIBD, forms a significant component of the routine workload in most tissue pathology laboratories. In this review, we have chosen selected areas of particular diagnostic difficulty in CIBD pathology, providing key advice for pathology reporting. Those mimics of CIBD which have the greatest potential for misdiagnosis are discussed, particularly the wide range of infectious colitides which represent possible diagnostic pitfalls. The most important distinguishing features between the two main forms of CIBD, ulcerative colitis and Crohn's disease, are addressed, first in relation to resection specimens, and then with emphasis on features which may also be diagnostically useful in endoscopic biopsy material. The importance of assessment of the index endoscopic specimen is stressed, before treatment has been instigated, along with careful correlation with clinical and endoscopic features. Problems in the assessment of post-surgical CIBD specimens are described and then the role of upper gastrointestinal pathology specimens in diagnosing both Crohn's disease and ulcerative colitis, with increased recognition of upper gastrointestinal tract involvement in the latter condition. Finally, with recent developments in endoscopic surveillance techniques and local excision options, modern approaches to reporting and managing neoplasia complicating CIBD are reviewed.

Abstract
Granulomas are organised collection of activated histiocytes induced by a persistent antigen stimulus. A wide variety of antigens encountered by the gastrointestinal tract are of this nature and hence the resulting granulomatous inflammation represents a tissue reaction pattern. The potential causes can be broadly classified as infections or non-infectious immune reactions. There is also a group where a cause is never identified. Granulomas may be of varying morphological appearance, most commonly epithelioid, foreign body type, suppurative and necrotizing. This may provide a clue as to the aetiology; however, in most cases, the cause requires further inquiry. Pathologists may need to cut deeper levels to look for foreign material and apply special stains to look for microorganisms. Pathologists also need to be certain that the process is a true granuloma and not a mimic. The site of occurrence in the gastrointestinal tract and the clinical setting is often paramount in establishing the aetiology. For instance, infections are more likely the cause in developing countries or when there is immunosuppression. Similarly, granulomas in the stomach are usually due to Crohn's disease; however, it is only rarely the cause of granulomas isolated to the appendix.

Abstract
Since the notification of the first case of lymphogranuloma venereum (LGV) in the Czech Republic in 2010, the numbers of LGV cases have steadily increased in the country. In 2015, 40 LGV cases were diagnosed, bringing the total for 2010-2015, to 88 cases. The profile of the most affected group, HIV-positive men who have sex with men with a previous sexually transmitted infection, matches that of those described in LGV outbreaks in western Europe.

Abstract
Lymphogranuloma venereum (LGV) has emerged as an important cause of proctitis and proctocolitis in men who have sex with men; classical inguinal presentation is now increasingly uncommon. We report summary findings of an extensive literature review on LGV clinical presentation, diagnosis, and treatment that form the evidence base for the 2015 Centers for Disease Control and Prevention treatment guidelines for sexually transmitted diseases. Proctitis and proctocolitis are now the most commonly reported clinical manifestations of LGV, with symptoms resembling those of inflammatory bowel disease. Newer molecular tests to confirm LGV infection are sensitive and specific, but are generally restricted to research laboratory or public health settings. Doxycycline (100 mg twice daily for 21 days) remains the treatment of choice for LGV. Patients with rectal chlamydial infection and signs or symptoms of proctitis should be tested for LGV, or if confirmatory testing is not available, should be treated empirically with a recommended regimen to cover LGV infection.

Abstract
Endoscopic biopsies of the mucosa of the large and small intestines can present the pathologist with daunting challenges, in particular because of the breadth of the differential diagnosis, which may include neoplastic, ischemic, iatrogenic (notably medication related), autoimmune, idiopathic, and infectious entities. The purpose of the present study was to develop a logical and systematic approach to the diagnosis of mucosal infections by identifying several morphologic compartments in the intestinal mucosa, and establishing a differential diagnosis for the organisms that are associated with each compartment. The organisms involved may be identified by their appearances in histologic sections, or by the nature of the host reaction to their presence. The process of systematically examining each compartment of the mucosa and scanning for evidence of infection is performed subconsciously by many pathologists, and we have found this approach to be particularly appreciated by pathologists in training.

Abstract
CONTEXT The incidence of syphilis is on the rise, particularly in male patients who are human immunodeficiency virus (HIV) positive, and men who have sex with men. OBJECTIVE To describe 4 cases of primary syphilis presenting in the anal canal to increase awareness of its presentation and morphology in this location, as the diagnosis can be easily overlooked clinically and by the pathologist. Design .- Clinical presentation, hematoxylin-eosin-stained sections, and Treponema pallidum immunohistochemical staining were reviewed in detail in all 4 cases. RESULTS Three patients presented with anal canal ulcers; one presented with an ulcerated anal mass. All 4 patients were male, of whom 2 were HIV positive. Syphilis was clinically suspected in only 1 case; in 2 cases, confirmatory evaluation and treatment were prompted by pathologic diagnosis. In the fourth case, syphilis was diagnosed serologically at time of biopsy; however, the patient had an anal mass, and malignancy was clinically suspected. All 4 cases had bandlike chronic plasma cell-rich inflammation at the squamous epithelium and lamina propria junction; 2 cases had poorly formed granulomas. One case had concomitant rectal biopsy specimens with proctitis. Treponema pallidum immunohistochemistry highlighted homing of organisms in a perivascular pattern and at the junction of squamous epithelium and lamina propria. CONCLUSIONS Syphilis should be considered in the differential diagnosis of anal canal ulcers, anorectal inflammatory masses, and proctitis. Detailed knowledge of clinical history and recognition of the characteristic pattern of inflammation by the pathologist is important. Treponema pallidum immunohistochemical staining can help avoid a missed diagnosis of syphilis, which, if left unrecognized, can progress to late-stage disease with serious complications.

Abstract
OBJECTIVES Sexually transmitted infectious (STI) colitis often raises concern for inflammatory bowel disease (IBD). In this study, we compare histologic features of IBD with STI colitis caused by syphilis and lymphogranuloma venereum. METHODS The STI colitis group included 10 unique colorectal biopsy specimens in patients with clinically confirmed syphilis and/or lymphogranuloma venereum. The STI biopsy specimens were compared with patients matched for age, sex, and site with Crohn disease (n = 10) or ulcerative colitis (n = 10). All IBD controls had an established history of IBD (up to 276 months of follow-up, mean follow-up = 102 months). RESULTS Discriminating features (P < .05) of STI colitis included its exclusive identification in human immunodeficiency virus-positive men who have sex with men, anal pain, and anal discharge. STI colitis contained the triad of (1) minimal active chronic crypt centric damage, (2) a lack of mucosal eosinophilia, and (3) submucosal plasma cells, endothelial swelling, and perivascular plasma cells. Nondiscriminating features (P > .05) included rectal bleeding, endoscopic appearance, skip lesions, ulcerations, aphthoid lesions, granulomata, foreign body giant cells, neural hyperplasia, fibrosis, and lymphoid aggregates. CONCLUSIONS While STI colitis shares many overlapping features with IBD, histologic and clinical discriminating features may be helpful when confronted with that differential diagnosis.

Abstract
This review summarizes a variety of clinical and histologic mimics of idiopathic inflammatory bowel disease. All the entities that are included demonstrate one or more histologic features typical of idiopathic inflammatory bowel disease that may lead to potential diagnostic confusion and misinterpretation by the pathologist. The elements of the clinical history, laboratory test results, and endoscopic findings that are helpful to the surgical pathologist in considering a diagnosis other than idiopathic inflammatory bowel disease are emphasized. On occasion, a poor response to standard treatment for idiopathic inflammatory bowel disease is the clue that prompts reconsideration of the initial diagnosis. Subtle histologic features, special stains, or other diagnostic methodologies that can aid in proper diagnosis are also discussed.

Abstract
Proctitis is defined as an inflammatory syndrome of the distal 10-12 cm of the anal canal, also called the rectum. Infectious proctitis can be sexually transmitted via genital-anal mucosal contact, but some also via mutual masturbation.N. gonorrhoeae,C. trachomatis(including lymphogranuloma venereum), Herpes Simplex Virus andT. pallidumare the most common sexually transmitted anorectal pathogens. Shigellosis can be transferred via oral-anal contact and may lead to proctocolitis or enteritis. Although most studies on these infections have concentrated on men who have sex with men (MSM), a significant proportion of women have anal intercourse and therefore may also be at risk. A presumptive clinical diagnosis of proctitis can be made when there are symptoms and signs, and a definitive diagnosis when the results of laboratory tests are available. The symptoms of proctitis include anorectal itching, pain, cramps (tenesmus) and discharge in and around the anal canal. Asymptomatic proctitis occurs frequently and can only be detected by laboratory tests. The majority of rectal chlamydia and gonococcal infections are asymptomatic. Therefore when there is a history of receptive anal contact, exclusion of anorectal infections is generally indicated as part of standard screening for sexually transmitted infections (STIs). Condom use does not guarantee protection from bacterial and protozoan STIs, which are often spread without penile penetration.

Abstract
The interpretation of colorectal biopsies taken for the initial diagnosis of chronic idiopathic inflammatory bowel disease (IBD) is challenging. Subclassification of IBD as ulcerative colitis (UC) or Crohn's disease, which may be particularly difficult, is the subject of this review. Biopsies taken at first presentation are emphasised, partly because their features have not been modified by time or treatment. Aspects of longstanding disease and of resections are also mentioned. The first part of the review comprises background considerations and a summary of histological features that are discriminant, according to published evidence, between UC and Crohn's disease in initial biopsies. Pitfalls and problems associated with making the distinction between UC and Crohn's disease are then discussed. These include: mimics of IBD; inadequate clinical details; unreliable microscopic features; absence of histological changes in early IBD; discontinuity in UC; cryptolytic granulomas; differences between paediatric and adult UC; reliance on ileal and oesophagogastroduodenal histology; and atypical features in IBD resections. Avoidance by pathologists of known pitfalls should increase the likelihood of accurate and confident subclassification of IBD, which is important for optimum medical and surgical management.

Abstract
Accurate histopathological assessment of biopsies is important for the diagnosis, subclassification, and management of chronic idiopathic inflammatory bowel disease (IBD). British Society of Gastroenterology (BSG) guidelines for the initial histopathological diagnosis of IBD were published in 1997. Changes since then include: more widespread use of full colonoscopy; greater recognition of the effects of time and treatment; improved documentation of variations in anatomical distribution; better understanding of the mimics of IBD; significant progress in clinical management; and modifications of terminology. Accordingly, an update is required. These revised guidelines aim to optimise the quality and consistency of reporting of biopsies taken for the initial diagnosis of IBD by summarising the literature and making recommendations based on the available evidence. Advice from existing clinical guidelines is also taken into account. Among the subjects discussed are: distinguishing IBD from other colitides, particularly infective colitis; subclassification of IBD (as ulcerative colitis, Crohn's disease, or IBD unclassified); the discriminant value of granulomas; aspects of disease distribution, including discontinuity in ulcerative colitis; time-related changes; differences between paediatric and adult IBD; the role of ileal and upper gastrointestinal biopsies; differential diagnoses such as diverticular colitis and diversion proctocolitis; and dysplasia. The need to correlate the histological features with clinical and endoscopic findings is emphasised. An approach to the conclusion of an IBD biopsy report based on the acronym Pattern, Activity, Interpretation, Dysplasia (PAID) is suggested. The key recommendations are listed at the end of the document.
