Abstract
BACKGROUND Confusion exists regarding interstitial granulomatous dermatitis (IGD) and palisaded neutrophilic and granulomatous dermatitis (PNGD). OBJECTIVE To determine whether IGD and PNGD are two different entities, or whether they must be considered as two subtypes of the same reactive pattern, and thus whether the unification of the nomenclature is necessary. METHODS Observational retrospective multicentre study of patients with IGD and PNGD evaluated between 1999 and 2019 and review of their clinical and histological features. RESULTS We identified 52 patients (38 women and 14 men). Clinical and histological findings of IGD were observed in 88.4% of cases. The most common cutaneous lesions were plaques/macules (IGD) or annular plaques and papules/nodules (PNGD), located mostly on the limbs and trunk. The rope sign was developed in two patients with IGD that associated autoimmune disorders. Similar associated comorbidities (75%) were found in both entities, mainly autoimmune diseases (53.8%). In IGD, the infiltrate was predominantly lympho-histiocytic. Neutrophilic infiltrates, karyorrhexis and skin lesions with limited clinical course were mainly associated with PNGD biopsies. In biopsies with a limited recurrent course, a predominant lymphocytic inflammatory infiltrate was found. Collagen degeneration was present in 75.9% of cases. The floating sign was observed only in IGD type patients (63%). Overlapping histological findings were found in one fourth of cases, especially between IGD and interstitial granuloma annulare. Interface dermatitis, apparently unrelated to drug intake, was observed in 4 cases of IGD. CONCLUSION We support the term reactive granulomatous dermatitis to unify both the clinical and histological findings of IGD and PNGD, and the overlapping between IGD and interstitial granuloma annulare. According to this, a spectrum of histological changes will be found depending on the clinical course of the skin lesions.

Abstract
BACKGROUND Chemotherapy is considered the most appropriate treatment for metastatic uterine sarcoma, despite its limited efficacy. No other treatment has been conclusively proved to be a real alternative, but some reports suggest that anti-hormonal therapy could be active in a small subset of patients. We report the case of a patient with metastatic uterine carcinosarcoma with positive hormonal receptors and a complete pathological response. CASE PRESENTATION A 54-year-old white woman presented to our emergency room with hypovolemic shock and serious vaginal bleeding. After stabilization, she was diagnosed as having a locally advanced uterine carcinosarcoma with lymph nodes and bone metastatic disease. In order to control the bleeding, palliative radiotherapy was administered. Based on the fact that positive hormone receptors were found in the biopsy, non-steroidal aromatase inhibitor therapy with letrozole was started. In the following weeks, her general status improved and restaging imaging tests demonstrated a partial response of the primary tumor. Ten months after initiating aromatase inhibitor therapy, she underwent a radical hysterectomy and the pathological report showed a complete response. After completing 5 years of treatment, aromatase inhibitor therapy was stopped. She currently continues free of disease, without further therapy, and maintains a normal and active life. CONCLUSIONS This case shows that patients with uterine carcinosarcoma and positive hormone receptors may benefit from aromatase inhibitor therapy. A multidisciplinary strategy that includes local therapies such as radiation and/or surgery should be considered the mainstay of treatment. Systemic therapies such as hormone inhibitors should be taken into consideration and deserve further clinical research in the era of precision medicine.

Abstract
OBJECTIVE To compare diagnostic performance of preoperative transvaginal ultrasound (TVS) and intraoperative macroscopic examination for determining myometrial infiltration in women with low-risk endometrial cancer, and to estimate the agreement between the two methods. METHODS This was a single-center observational study comprising women with preoperative diagnosis of well- or moderately differentiated endometrioid carcinoma of the endometrium. All women underwent preoperative TVS by a single examiner. According to the examiner's subjective impression, myometrial infiltration was stated as ≥ 50% or < 50%. Surgical staging was performed in all cases. Intraoperative macroscopic examination of the removed uterus was performed by pathologists who were unaware of the ultrasound findings, and myometrial infiltration was stated as ≥ 50% or < 50%. Definitive histological diagnosis of myometrial infiltration was made by frozen section analysis and was used as the gold standard. Sensitivity and specificity with 95% CIs were calculated for TVS and intraoperative macroscopic inspection and compared using McNemar's test. Agreement between TVS and intraoperative macroscopic inspection was estimated using Cohen's kappa index (κ) and percentage of agreement. RESULTS Of 209 eligible women, 152 were ultimately included. Mean (± SD) age was 60.9 ± 10.2 years, with a range of 32-91 years. Definitive histological diagnosis revealed that myometrial infiltration was < 50% in 114 women and ≥ 50% in 38 women. Sensitivity and specificity of TVS for detecting deep myometrial infiltration were 81.6% and 89.5%, respectively, whereas the respective values for intraoperative macroscopic examination were 78.9% and 90.4% (McNemar's test, P > 0.05 when comparing TVS and intraoperative macroscopic examination). Agreement between methods was moderate with κ = 0.54 (95% CI, 0.39-0.69) and percentage of agreement of 82%. CONCLUSIONS Although the agreement between preoperative TVS and intraoperative macroscopic examination for detecting deep myometrial infiltration was only moderate, both methods had similar accuracy when compared with frozen section histology. Preoperative TVS might reasonably be proposed as a method for assessing myometrial infiltration as an alternative to intraoperative macroscopic examination, especially when performed by an experienced examiner and image quality is not poor.

Abstract
BACKGROUND 2D7 and BB1 are thought to be basophil-specific markers. In this study, we tested both antibodies in different skin and mast cell disorders with the aim of determining whether it was possible to differentiate between benign and aggressive presentations of mastocytosis. METHODS Using the antibodies 2D7, BB1, and c-Kit, we performed an immunohistochemical study of skin biopsy specimens from patients with cutaneous mastocytosis (15 urticaria pigmentosa and telangiectatic macularis eruptive perstans) and liver or bone marrow biopsy specimens from patients with systemic mastocytosis. A basophil leukemia cell line was used as a reference. Peripheral blood basophils from healthy donors were used as controls. RESULTS We observed intense expression of 2D7 and BB1 in all skin biopsy specimens from patients with cutaneous mastocytosis. Immunostaining of liver and bone marrow specimens from patients with systemic mastocytosis with 2D7 and BB1 antibodies was negative. Specimens from patients with either type of mastocytosis showed similarly strong expression of c-Kit. The basophil cell line showed a 2D7 and a BB1 profile, with intense expression of c-Kit. Peripheral blood basophils exhibited notable immunostaining for 2D7, BB1, and c-Kit. CONCLUSIONS 2D7 and BB1 are expressed in cutaneous mastocytosis, although this expression is lost when mast cell proliferation is systemic, thus reflecting either a different cellular differentiation stage or the presence of basophils in these skin diseases.

Abstract
The Peutz-Jeghers syndrome (PJS) is an autosomal dominant hamartomatous poliposis describred in 1921. Hemminki in 1997 described the presence of LKB-1 mutation tumor-suppressor gen.The patients with PJS develop a higher cumulative incidence of gastrointestinal, pancreas and extraintestinal tumors, being occasion of a renew interest on hamartomatous polyposis syndromes regarding the clinical care, cancer surveillance treatment and long term follow-up.We report the case of a 38 years old male, diagnosed of PJS who developed a multiple adenocarcinoma in duodenum and yeyunum. Surgically treated and with a long-term free disease survival of 11 years represents the sixth case reported in the spanish literature of PJS associated with a gastrointestinal tumor.A critical review, molecular alterations and the established criteria of tumor screening and surveillance are reviewed.

Abstract
Waldenström macroglobulinemia is a blood dyscrasia characterized by monoclonal proliferation of B cells in the bone marrow, lymph nodes, and spleen. Patients with this disease show elevated serum levels and tissue deposition of monoclonal immunoglobulin (Ig) M produced by these aberrant cells. We present the case of a patient with Waldenström macroglobulinemia who suffered cutaneous lesions resulting from deposition of k light chains of IgM and clinical manifestations secondary to associated type I cryoglobulinemia. We discuss the different pathological cutaneous processes caused by IgM in Waldenström macroglobulinemia.

Abstract
We report the case of a fiftyone-year-old woman with a past medical history of Linfoma no Hodking and a gastric adenocarcinoma with signet ring cells. She came to our institution with a twenty month history of dysnea secondary to pleural effussion, bilateral lower extremity edema and probably had ascitis. On CT and US two bilateral pelvic masses were found and biopsied. The anatomopathological analysis showed bilateral ovarian implants from signet ring cell adenocarcinoma (Krukenberg tumor). This patient developed a PseudoMeigs syndrome consisting on malignant ovarian tumor asociated with ascitis and pleural effusion without malignant cells. Oncological patients who present with ascitis and benign pleural effusion, the diagnosis of PseudoMeigs syndrome should be considered.

Abstract
AIM To review the current state of the classification and oncogenesis of gliomas, emphasizing those biologic parameters with special clinical significance. DEVELOPMENT In the current classification, both histologic grade and phenotype are considered the pathological features with more relevant clinical impact. These factors are an obligatory reference for both all molecular studies and a new classification. The relationship between the oligodendroglial phenotype and the loss of chromosomes 1p and 19q is a useful data in the histopathologic differential diagnosis. The new pathologic-molecular classification should take into account the current state of knowledge about the malignization pathways of gliomas, which have prognostic significance. The neoplastic biological potential should be determined in each case according with the tumoral heterogeneity. Then, this evaluation can be based on tumoral microdissection. Although no well established prognostic molecular profiles are available, several molecular alterations are relevant such as chromosome 10 deletion, especially of the 10q23 region, mutation of PTEN and TP53 genes and amplification or mutation of EGFR. For treatment purposes, the combined deletion 1p/19q identifies the anaplastic type of oligodendrogliomas that are more responsive to chemotherapy. CONCLUSIONS The new pathomolecular classification of gliomas should improve the old one, especially being concerned about the oncogenesis and heterogeneity of these tumors. It is desirable that this classification has clinical applicability and can integrate new molecular findings with some known histological features with prognostic value.

Abstract
PTEN gene (10q23) is a relevant tumor suppressor gene whose protein is a phosphatase involved in the control of angiogenesis of some tumors including astrocytomas. There are no studies correlating molecular changes of PTEN and the immunohistochemical expression of its protein (pPTEN) with the expression of vascular endothelial growth factor (VEGF) in astrocytomas. Fifty-six surgically resected brain gliomas, 10 grade 2, 16 grade 3, and 30 grade 4, were studied by a combined approach, consisting of (1) PCR analysis using four microsatellite markers against the PTEN gene region (10q23), (2) the FISH technique to test chromosome 10 using a pericentromeric probe, and (3) immunohistochemical evaluation of pPTEN and VEGF. Loss of heterozygosity (LOH) of PTEN was observed in 10% of fibrillary grade 2 astrocytomas and all gemistocytic ones. In high-grade tumors, LOH was more frequent in grade 4 than in grade 3 (> or =2 loci deleted, 83% and 56%, respectively). Monosomy for chromosome 10 was observed especially in high-grade tumors (6% of grade 3 and 50% of grade 4) and in 20% of grade 2 tumors, corresponding to gemistocytic astrocytomas. Results with both antibodies against PTEN were concordant: loss of cytoplasmic immunoreactivity was frequently observed according to homogeneous or heterogeneous patterns in 70% and 50% of grades 4 and 3, respectively, but not in grade 2. Immunonegativity of pPTEN was associated with PTEN gene deletion (> or =2 loci deleted) (P = 0.04) but not with monosomy. Cytoplasmic immunoreactivity against VEGF was observed in high-grade and in gemistocytic astrocytomas, but not in conventional grade 2 tumors. Tumor expression of pPTEN was not associated with immunoreactivity against VEGF when the same areas were considered. In conclusion, loss of PTEN expression is frequent in high-grade astrocytomas, but not in grade 2 tumors, and correlates with PTEN deletion and loss of chromosome 10. PTEN immunoreactivity does not correlate with VEGF expression in astrocytomas when similar areas are considered.

Abstract
Cutaneous metastases from internal malignancies or primary skin cancers are uncommon, and a zosteriform pattern is very rare. Histologically, these cutaneous metastases usually appear as malignant epithelial cells located throughout the dermis or subcutaneous fat and without connection to the overlying epidermis. The presence of melanocytes in such lesions is atypical. Moreover, although zosteriform cutaneous metastases of cutaneous squamous cell carcinoma have previously been described in immunosuppressed patients, they have not been reported in immunocompetent patients. We report an unusual case of a woman with cutaneous hyperchromic zosteriform metastases, clinically mimicking a metastatic melanoma but appearing histologically as epidermotropic and pigmented metastases of a cutaneous squamous cell carcinoma.

Abstract
Epidermolytic acanthoma is a rare benign tumour, which may occur in both isolated and disseminated forms. Only seven cases of disseminated epidermolytic acanthoma (DEA) have been described. This entity should be distinguished from other hereditary or acquired conditions which involve epidermolytic hyperkeratosis and other benign acanthomas. On the basis of the clinical history and the histological findings, we diagnosed a case of DEA which was probably secondary to repeated trauma.

Abstract
The aim of this study was to elucidate the neuropathological substrate of intestinal failure before and after small bowel transplantation (SBT). Retrospective analysis of complete autopsy or brain biopsy specimens of 17 patients with intestinal failure (12 children and 5 adults) were studied. Patients were divided into two groups. Group I (transplanted group; n = 13) included those patients who underwent intestinal transplantation under tacrolimus and steroids immunosuppressive therapy. Group II (control group) included 4 children with intestinal failure who were candidates for SBT and died while awaiting an intestinal allograft. Central nervous system (CNS) abnormalities were seen in 92% of the SBT recipients and in 100% of SBT candidates. The neuropathological lesions of SBT recipients included: (a) vascular lesions: global brain ischemia, infarcts, intracranial hemorrhage and edema (7 children/2 adults; 69%); (b) cerebral atrophy (6 children; 46%); (c) Alzheimer type II gliosis (5 children/4 adults; 69%); (d) infection (3 patients; 23%) due to cytomegalovirus (1 child), Aspergillus fumigatus (1 adult) and progressive multifocal leukoencephalopathy (PML)-like (1 adult); (e) Epstein-Barr virus-related cerebral post-transplant lymphoproliferative disorder (2 children; 15%); and (f) central pontine and extrapontine myelinolysis (1 child; 7.5%). The neuropathological lesions of SBT candidates were Alzheimer type II astrocytosis (4 patients), vascular changes (4 patients), brain atrophy (4 patients) and cerebral candidiasis (1 patient). CNS vascular, metabolic and infectious pathology are significant causes of morbidity and mortality in patients suffering intestinal failure, both before and after SBT. Brain atrophy was a frequent finding and may be related to nutritional and developmental inadequacy of long-term total parenteral nutrition.

Abstract
The use of bioreductive agents in enzyme-directed bioreductive therapy has been proposed to take advantage not only of hypoxia in tumours, but also of the presence of reductases that metabolise such compounds. In this study, we studied the activities of NADPH cytochrome P450 reductase (P450R) and carbonyl reductase (CR) in 17 human lung tumours and 18 human breast tumours, together with the corresponding normal tissues. For lung cancer but not for breast cancer there was a significant difference in the CR activity between normal and tumour tissue. CR activity was increased with respect to the normal tissue between 2-fold and 40-fold indicating heterogeneity in tumour samples. No relationship was found between CR activity and the histological type, tumoral grade or TNM stage of the tumours. Although some variation in P450R activity in tumoral versus normal tissues was found in the majority of the samples studied, no significant differences could be demonstrated.

Abstract
We report a case of a 13-year-old girl with soft tissue sarcoma of the hand, which showed muscle and neuroectodermal immunophenotypes. Molecular studies were performed on RNA collected from fine-needle aspiration (FNA) cytology and peripheral blood samples by nested reverse transcriptase-polymerase chain reaction (RT-PCR) and Southern blot analysis. This biphenotypic tumor showed simultaneous expression of EWS-FLI1 and PAX3-FKHR transcripts, specific of Ewing family tumors and alveolar rhabdomyosarcoma, respectively. Although childhood sarcomas with simultaneous muscle and neural differentiation have been described to have EWS-FLI1 transcripts, there are no reports of tumors with both transcripts. Cytological specimens are a good source of RNA for molecular studies.

Abstract
The level of expression of enzymes that can activate or detoxify bioreductive agents within tumours has emerged as an important feature in the development of these anti-tumour compounds. The levels of two such reductase enzymes have been determined in 19 human non-small-cell lung tumours and 20 human breast tumours, together with the corresponding normal tissue. DT-diaphorase (DTD) enzyme levels (both expression and activity) were determined in these samples. Cytochrome b5 reductase (Cytb5R) activity was also assessed. With the exception of six patients, the levels of DTD activity were below 45 nmol min(-1) mg(-1) in the normal tissues assayed. DTD tumour activity was extremely variable, distinguishing two different groups of patients, one with DTD activity above 79 nmol min(-1) mg(-1) and the other with levels that were in the same range as found for the normal tissues. In 53% of the lung tumour samples, DTD activity was increased with respect to the normal tissue by a factor of 2.4-90.3 (range 79-965 nmol min[-1] mg[-1]). In 70% of the breast tumour samples, DTD activity was over 80 nmol min(-1) mg(-1) (range 83-267 nmol min[-1] mg[-1]). DTD expression measured by Western blot correlated well with the enzyme activity measured in both tumour and normal tissues. The levels of the other reductase enzyme, Cytb5R, were not as variable as those for DTD, being in the same range in both tumour and normal tissue or slightly higher in the normal tissues. The heterogeneous nature of DTD activity and expression reinforces the need to measure enzyme levels in individual patients before therapy with DTD-activated bioreductive drugs.

Abstract
Salivary gland ducts play a relevant role in saliva secretion through transport processes. Na(+)-independent chloride-bicarbonate anion exchangers (AE) may be involved in these processes by generating ion fluxes into the salivary secretion. In Sjögren's syndrome, a disorder with gland dysfunction, there might be an impaired expression of AE proteins. Here we study AE immunoreactivities in human salivary glands, both in health and in Sjögren's syndrome. Immunohistochemistry was carried out on salivary glands from normal subjects and patients with Sjögren's syndrome, using two monoclonal antibodies against AE1 and AE2. Normal salivary glands showed AE2 immunoreactivity, which was restricted to the epithelium of the ducts, with no staining at the acini. A strong positivity was seen in the basolateral portion of the striated ducts, while interlobular duct cells showed a discrete positivity at their apical pole. In salivary glands from most of the patients with Sjögren's syndrome, AE2 immunoreactivity was absent in the ducts as well as in the acini. In both normal and diseased salivary glands, AE1 immunoreactivity was only located at the erythrocyte membrane. The recently reported AE0 was discarded because no AE0 message was found in salivary glands by reverse transcription polymerase chain reaction. In conclusion, AE2 immunoreactivity is observed in the ducts of normal salivary glands, particularly in the striated ducts. AE2 immunoreactivity is virtually absent in salivary glands from patients with Sjögren's syndrome, which may reflect either a loss of AE2 after inflammatory atrophy, or a primary defect occurring in the disease.

Abstract
We report a heart transplant recipient who developed graft-versus-host disease (GVHD) following blood transfusion. We consider that heart transplant recipients should be included in the category of immunosuppressed patients who may develop this disease after being treated with blood products. We also consider that, at the present time, irradiation of blood products is the only useful method of avoiding development of GVHD in these patients.

Abstract
Collagenous colitis (CC) is a newly recognized entity characterized clinically by chronic watery diarrhoea and pathologically by epithelial inflammatory injury and the presence of a thickened collagen band beneath the surface epithelium of the colon. Clinical and pathological data of six patients (5 women and 1 man, mean age 54 years) with this diagnosis have been reviewed. Chronic watery diarrhoea was the main symptom in all cases, ranging from 2 to 12 bowel movements a day (mean +/- SD, 5.5 +/- 2.3) lasting from 8 months to 19 years (mean +/- SD, 6.6 +/- 5.9 years). Laboratory, barium and endoscopic studies showed unspecific findings. Rheumatic and thyroid diseases as well as drug allergies were found in five cases. The cause of collagenous colitis and the mechanism of diarrhoea remains undefined, being the inflammatory and autoimmune hypothesis the most likely. Diagnosis was made by multiple rectal and colonic biopsies. Pathologic findings characteristic of CC were more prominent in proximal than in distal colonic specimens. Different treatments were applied and diverse clinic responses were obtained. A review of the literature is made.

Abstract
Cyanamide, a drug used in alcohol aversion therapy, induces a distinctive liver cell lesion, both in human beings and rats. The lesion consists of cytoplasmic inclusion bodies which give a ground-glass appearance to the hepatocytes. In human beings the inclusion bodies do not persist but disappear some time after withdrawal of the drug. In order to confirm their disappearance and determine how they regress rats were treated with cyanamide (32 mg/kg) for 6 months before partial lobectomy. At this time, inclusion bodies were observed. After a period without further treatment (5-19 weeks) the animals were killed and a marked decrease in the number of inclusion bodies was observed, paralleling the period of time without treatment. Inclusion bodies regress as a result of glycogen removal by enzymatic activity of the smooth endoplasmic reticulum which then undergoes hyperplasia, plus a process of autophagocytosis and necrosis of inclusion-body-bearing hepatocytes which are then phagocytosed by macrophages.

Abstract
Perianal basal cell carcinoma (BCC) is a rare tumour and only a few case reports can be found in the literature. In this location, it is important to differentiate a BCC from a basaloid cloacogenic carcinoma, as the first is an invasive but localized tumour, while the second has a high capacity for metastasis.

Abstract
An unusual case of Anderson-Fabry's disease with renal damage and bilateral corneal deposits but without angiokeratomas is presented. Diagnosis was made by renal biopsy. Typical foamy transformation of endothelium, mesangium, tubular epithelial cells, vascular smooth muscle, and fibroblasts of kidney biopsy and similar changes of myoepithelial, perineural, and endothelial cells on the skin biopsy were observed. At electron microscopy, 'fingerprint-like' myelin figures were seen. The epithelial cells of eccrine sweat glands showed striking vacuolation but myelin figures were not seen. We suggest that electron microscopic study of skin biopsies is indicated in the evaluation of patients clinically suspected of having Fabry's disease.

Abstract
A case of Lafora's disease diagnosed by skin biopsy is reported. Lafora's bodies, the hallmark of myoclonal epilepsy, were present in the epithelial cells of the apocrine glands. Therefore, the skin biopsy of the axilla proved to be very useful in the diagnosis of this entity. A striking feature of the case was that Lafora's bodies were only found in apocrine glands, whereas the eccrine glands were free of them.

Abstract
Two patients developed non-Hodgkin's lymphoma (NHL) six and ten years after radiotherapy and chemotherapy for Hodgkin's disease nodular sclerosis type. The histological classification of the developing NHL for the two patients was: IgG (K) secreting lymphoplasmacytoid lymphoma of the stomach, and immunoblastic lymphoma of the cervical lymph nodes. Both patients responded well to conventional chemotherapy for NHL and are alive 22 and 5 months after the diagnosis of the secondary tumor. Forty eight cases of NHL after treatment for HD have been previously reported. We present a review of the literature of these cases, adding to this literature the first reported case of gastric lymphoplasmacytoid lymphoma under such circumstances.
