Small bowel perforation due to CMV enteritis infection in an HIV-positive patient

BACKGROUND

Cytomegalovirus infection of the gastrointestinal tract is common and is more often seen in patients with acquired immunodeficiency syndrome (AIDS). Although small bowel infection is less common than infection of other parts of the gastrointestinal system, it may lead to perforation, an acute complication, with dreadful results.

CASE PRESENTATION

This article reports a case of Cytomegalovirus ileitis with multiple small bowel perforations in a young man with human immunodeficiency virus (HIV) infection. The patient developed abdominal pain with diarrhea and fever, and eventually acute abdomen with pneumoperitoneum. The patient had poor prognosis and deceased despite the prompt surgical intervention and the antiviral therapy he received. At pathology a remarkable finding was the presence of viral inclusions in smooth muscle fibers. The destruction of muscle cells was the main cause of perforation.

CONCLUSION

Morbidity and mortality associated with perforation from CMV enteritis in AIDS patients are high and the life expectancy is short. Cytomegalovirus disease is multifocal; therefore, excision of one portion of the gastrointestinal tract may be followed by a complication elsewhere. Our case elucidate that muscle cell destruction by the virus is a significant cause leading to perforation.

Adrenal Gland Lymphangiomas

Lymphangiomas of the adrenal glands (ALs) are benign vascular lesions. Approximately, 53 cases have been reported in the literature. The current study reviews and analyzes the clinical and pathologic features of all reported ALs and additionally illustrates a typical case of adrenal lymphangioma (AL). In order to perform the review analysis, a search of the international literature for ALs in adults was conducted. Thirty-eight related articles were found. Clinical and pathological information were obtained for all the reported cases and a database was created. ALs were detected more frequently in women than men. The mean age of occurrence was 39.5 years, while their mean size was 8.86 cm. Fifty-nine percent of ALs were right-sided. Size and localization were responsible for the presenting symptoms, though 30.4 % were asymptomatic. Diagnosis was made postoperatively in all cases by histological results. ALs are rare and benign lesions. They usually present as an incidental finding after abdominal imaging. The diagnosis is made after the surgical removal by histological and immunohistochemical examinations.

Squamous cell carcinoma arising from chronic sacrococcygeal pilonidal disease: a case report

Background

Sacrococcygeal pilonidal disease is a chronic, well-recognized entity, characterized by the recurrent formation of an abscess or draining sinus over the sacrococcygeal area. It is one of the most common surgical problems. Rarely, chronic inflammation and recurrent disease leads to malignant transformation, most commonly to squamous cell carcinoma (SCC).

Case presentation

We describe an extremely unusual case of SCC developing in a 60-year-old patient with a chronic pilonidal sinus complicated by an anal fistula. After wide surgical excision of the pilonidal sinus and fistulas and because of the poor healing process 6 months later, colonoscopy and a percutaneous fistulography were performed, revealing an anal canal-pilonidal fistula. Patient was treated with a more radical surgical resection with a prophylactic loop colostomy, but healing was not accelerated. Multiple biopsies were then taken from the surgical site at the time, which revealed the development of SCC. CT and MRI imaging techniques revealed SCC partial invasion of the coccyx and sacrum. As a result, aggressive surgical approach was decided. Histological examination revealed moderately to poorly differentiated SCC, and the patient was treated with adjuvant radiation therapy postoperatively. Nine months later, recurrence was found in the sacrum and para-aorta lymph nodes and the patient died shortly after. We discuss the clinical features, pathogenesis, treatment options, and prognosis of this rare malignant transformation.

Conclusions

The development of SCC in chronic pilonidal disease is a rare but serious complication. Symptoms are usually attributed to the sacrococcygeal pilonidal disease (SPD), and diagnosis is often made late by histological examination of biopsies. Malignant transformation should be suspected in chronic SPD with recurrent episodes of inflammation, repeated purulent discharge, poor healing, and chronic complex fistulas.

Rupture of right hepatic duct into hydatid cyst

Echinococcal disease can develop anywhere in the human body. The liver represents its most frequent location. Hepatic hydatid cysts may rupture into the biliary tract, thorax, peritoneum, viscera, digestive tract or skin. We report a rare case with rupture of the right hepatic duct into a hydatid cyst in a woman with known hydatid disease and choledocholithiasis. The increased intra-luminal pressure in the biliary tree caused the rupture into the adjacent hydatid cyst. The creation of the fistula between the right hepatic duct and the hydatid cyst decompressed the biliary tree, decreased the bilirubin levels and offered a temporary resolution of the obstructive jaundice. Rupture of a hydatid cyst into the biliary tree usually leads to biliary colic, cholangitis and jaundice. However, in case of obstructive jaundice due to choledocholithiasis, it is possible that the cyst may rupture by other way around while offering the patient a temporary relief from his symptoms.

Typical image of splenic hydatidosis

This is a typical case of a splenic hydatid cysts. We present the clinical features, the diagnostic work-up and the management of the disease.

Laparoscopic spleen-preserving distal pancreatectomy in a solitary true pancreatic cyst

BACKGROUND

Solitary true pancreatic cysts (STPCs), or epithelial cysts, are benign lesions that are extremely rare in adult patients. Advances in radiographic techniques have improved the ability to identify pancreatic cystic lesions. We report a case of a large and symptomatic STPC in a 47-year-old female patient who was treated successfully with spleen-preserving laparoscopic distal pancreatectomy. We also review the clinical and pathologic features of all reported STPCs within the past 25 years.

DATABASE

To compose the review, we did a search of the international literature for STPCs that had occurred in adults. Fourteen related articles were found describing cases of STPCs. Clinical and pathologic information was collected for all of the reported pancreatic cysts, and a database was formed. STPCs are detected more frequently in women than in men. The mean age of occurrence is 43.2 years, and the mean cyst size is 5.6 cm. Fifty percent of true cysts are located in the head of the pancreas. Size and site are responsible for the symptoms caused, although 22.8% were asymptomatic. Diagnosis was made postoperatively in all cases by histopathologic studies. No case of malignancy was reported in any STPC.

CONCLUSIONS

STPCs are rare and benign lesions commonly discovered incidentally during abdominal imaging. Surgical treatment is considered the appropriate therapy for large and symptomatic STPCs. The definitive diagnosis is established by histopathologic and immunohistochemical studies.

Pharmaceutical Management of Secondary Hyperparathyroidism and the Role of Surgery: A 5-Year Retrospective Study

Background and Objectives: Secondary hyperparathyroidism (SHPT) poses a common condition among patients with chronic kidney disease (CKD) due to the chronic stimulation of the parathyroid glands as a result of persistently low calcium levels. As a first option for medical treatment, vitamin D receptor analogs (VDRAs) and calcimimetic agents are generally used. Apart from cinacalcet, which is orally taken, in recent years, another calcimimetic agent, etelcalcetide, is being administered intravenously during dialysis. Materials and Methods: In a 5-year retrospective study between 2018 and 2023, 52 patients undergoing dialysis were studied. The aim of this study is to highlight the possible effects and/or benefits that intravenously administered calcimimetic agents have on CKD patients. A total of 34 patients (65.4%) received cinacalcet and etelcalcetide while parathormone (PTH) and calcium serum levels were monitored on a monthly basis. Results: A total of 29 out of 33 patients (87.9%) that received treatment with etelcalcetide showed a significant decrease in PTH levels, which rose up to 57% compared to the initial values. None of the included patients needed to undergo parathyroidectomy (PTx) due to either extremely high and persistent PTH levels or severe side effects of the medications. It is generally strongly advised that parathyroidectomies should be performed by an expert surgical team. In recent years, a significant decrease in parathyroidectomies has been recorded globally, a fact that is mainly linked to the constantly wider use of new calcimimetic agents. This decrease in parathyroidectomies has resulted in an important decrease in complications occurring in cervical surgeries (e.g., perioperative hemorrhage and nerve damage). Conslusions: Despite the fact that these surgical complications cannot be easily compared to the pharmaceutical side effects, the recorded decrease in parathyroidectomies is considered to be notable, especially in cases of relapse where a difficult reoperation would be considered based on previously published guidelines.

Impact Of Comorbidities On Outcomes And Healthcare Costs Of Open Inguinal Hernia Repair In Patients With Diabetes Mellitus

INTRODUCTION

Inguinal hernia management in patients with diabetes mellitus (DM) and comorbidities presents challenges due to potential impacts on wound healing and infection risk. This study evaluates the influence of additional comorbidities on outcomes following open inguinal hernia repair in DM patients.

MATERIAL AND METHODS

A retrospective cohort study was conducted at Craiova Emergency Clinical County Hospital from 2015 to 2020. Patients with documented DM undergoing hernia repair were categorized into two groups based on comorbidity status. Data on presentation mode, hernia type, comorbidities, hospitalization, operative details, postoperative outcomes, and costs were collected and analyzed statistically.

RESULTS

Among 38 DM patients undergoing hernia repair, 16 were in Group A (DM alone) and 22 in Group B (DM with comorbidities). Group B patients were older (p = 0.0002) and more likely to present emergently (OR: 13.81, p=0.0148) with incarcerated (OR: 22.733, p=0.0339) or strangulated hernias (OR: 9.4545, p=0.0390). Group B had longer hospitalizations (p=0.00132) and higher hospitalization costs (p = 0.00262).

CONCLUSIONS

DM patients with comorbidities are at higher risk for complex hernias and prolonged hospitalizations. Pulmonary fibrosis emerges as a significant comorbidity requiring specific perioperative strategies. Tailored preoperative assessments and care plans can optimize outcomes.

Neuroendocrine Breast Carcinoma: Interesting Images of an Underdiagnosed Entity

Breast cancer is the most common type of cancer of the female gender. A rare subtype of breast cancer is the invasive breast carcinoma (IBC) with neuroendocrine (NE) differentiation. Its incident is believed to be 0.1% to 5% of all breast cancers. We report a rare case of a 66-year old woman who presented with an isolated nodule of the left breast. The patient underwent modified radical mastectomy. Pathology revealed invasive breast carcinoma with neuroendocrine differentiation. Invasive breast carcinoma is an extremely rare group of neoplasms, the exact frequency of which cannot be determined with current data. Therefore, it is necessary for future studies to focus on the pathophysiology of this subtype of breast cancer and on the potential therapeutic approaches.

The role of prophylactic parathyroidectomy during thyroidectomy for MTC in patients with MEN2A syndrome

AIM

To define the role of prophylactic parathyroidectomy in the surgical treatment of medullary thyroid carcinoma (MTC) in multiple endocrine neoplasia type IIa (MEN2A) syndrome through a literature review.

The expression of c-MYC, Cyclin D1 and Ki-67/MIB-1 in benign and malignant thyroid tissues: is there any diagnostic value?

AIM

To investigate the immunohistochemical (IHC) expression and the diagnostic value of c-MYC, Cyclin D1, and Ki-67∕MIB-1 in follicular adenomas (FAs), follicular carcinomas (FCs), and anaplastic carcinomas (ACs) of the thyroid gland, as well as in their corresponding adjacent, non-neoplastic thyroid tissue (NNTT).

MATERIALS AND METHODS

We conducted a retrospective study of patients who were pathologically diagnosed with FA, FC, or AC after total thyroidectomy. Tissue microarrays with cores taken from neoplastic and adjacent NNTT were constructed. Immunohistochemistry for anti-c-MYC, anti-Cyclin D1, and anti-Ki-67∕MIB-1 antibodies was performed, and the positivity was evaluated.

RESULTS

Twenty-eight specimens were included. Nuclear c-MYC positivity was observed in 4∕11 FCs, and 3∕4 ACs, whereas cytoplasmic c-MYC positivity was found in 16∕24 NNTTs. Globally, there were statistically significant differences between neoplasms and NNTTs, with higher nuclear c-MYC and Cyclin D1 expression observed in neoplasms (p=0.017 and p=0.001, respectively). In contrast, cytoplasmic positivity was seen solely in NNTTs (p=0.001). Cyclin D1 positivity was noted in 11∕13 FAs, 7∕11 FCs, 2∕4 ATCs, and only in one NNTT. A statistically significant correlation was found between MIB1 and c-MYC nuclear positivity (p=0.040).

CONCLUSIONS

Our findings exhibit a clear difference in the IHC expression of c-MYC and Cyclin D1 between different types of thyroid tumors, as well as between the neoplastic and NNTT. Nuclear c-MYC positivity excludes the benign nature of a thyroid lesion, in contrast to cytoplasmic positivity, which demonstrates normal or hyperplastic nature.

Lymph node mapping helps in R0 resection for anaplastic thyroid carcinoma-report of a case with prolonged survival

Anaplastic thyroid carcinoma is a rare tumor, consisting 1–2% of all thyroid malignancies and presenting a high mortality rate. Median survival for patients undergoing primary surgery is approximately 6.6 months. We present a case of a patient treated with R0 resection, including total thyroidectomy and lymphadenectomy of levels III, IV, VI and VII after cervical lymph node mapping, oral 131I administration, and radiotherapy. Proper preoperative research, R0 resection and relatively early diagnosis, led to good prognosis, as the patient is currently totally disease-free, twelve months postoperatively.

A Unique Case of Appendiceal Intussusception (Inversion): A Case in Bloom

A 40-year-old female patient presented to a secondary facility with dull lower abdominal pain and a persistent low-grade fever. Her laboratory results showed elevated inflammation markers. A CT scan revealed two abscesses in the lesser pelvic region in direct contact with the apex of the appendix, the posterior wall of the uterus, and the right-side appendages. The patient responded well to intravenous antibiotics, and an MRI scan revealed the cause to be an appendiceal rupture. The patient was scheduled for an appendectomy. The procedure started laparoscopically but had to be converted to an open one with a midline infra-umbilical incision in order to protect the right appendages. A standard appendectomy was conducted, and the histology report revealed rupture of the appendix with concomitant wall inversion in the context of fibrous adhesions as well as obstruction due to a fecalith. Patient recovery and follow-up were excellent. Acute appendicitis, while frequently encountered in surgical practice, can present a diagnostic conundrum when it manifests in an atypical manner. This unique form of inversion appeared to confer a protective role against peritonitis, primarily through the mechanism of obstruction occurring centrally to the rupture. We suggest that this case should be included in current classifications as a partial inversion of the appendix after rupture and inflammation.

Tertiary hyperparathyroidism masking an atypical parathyroid tumor

Atypical parathyroid tumors represent a group of parathyroid neoplasms of uncertain malignant potential. In view of preoperative diagnostic difficulties, suspicious features for malignancy may guide the surgeon to perform a radical surgical approach.
