Abstract
In patients infected with human immunodeficiency virus (HIV), genital herpes can result in severe and atypical clinical presentations, and can become resistant to aciclovir treatment. Rarely, these manifestations may represent concurrent herpes simplex virus (HSV) with other agents. We report a 41-year-old black woman with HIV who presented with extensive and painful ulceration of the genitalia. Histological examination of a biopsy sample was suggestive of herpetic infection, and intravenous aciclovir was started, but produced only partial improvement. PCR was performed on the biopsy sample, and both HSV and cytomegalovirus (CMV) DNA was detected. Oral valganciclovir was started with therapeutic success. CMV infection is common in patients infected with HIV, but its presence in mucocutaneous lesions is rarely reported. This case exemplifies the difficulties of diagnosis of genital ulcers in patients infected with HIV. The presence of exuberant and persistent HSV genital ulcers in patients with HIV should also raise suspicions of the presence of co-infection with other organisms such as CMV.

Abstract
Myopericytoma (MPC) is a rare tumor with perivascular proliferation of pluripotent stem-cell-like pericytes. Although indolent, MPC may be locally aggressive with recurrent disease. The pathogenesis and diagnostic biomarkers of MPC are poorly understood. We discovered that 15% of benign MPCs (thyroid, skin; 3 of 20 samples) harbored BRAF(WT/V600E); 33.3% (1 of 3 samples) of BRAF(WT/V600E)-MPCs were multifocal/infiltrative/recurrent. Patient-MPC and primary MPC cells harbored BRAF(WT/V600E), were clonal and expressed pericytic-differentiation biomarkers crucial for its microenvironment. BRAF(WT/V600E)-positive thyroid MPC primary cells triggered in vitro (8.8-fold increase) and in vivo (3.6-fold increase) angiogenesis. Anti-BRAF(V600E) therapy with vemurafenib disrupted angiogenic and metabolic properties (~3-fold decrease) with down-regulation (~2.2-fold decrease) of some extracellular-matrix (ECM) factors and ECM-associated long non-coding RNA (LincRNA) expression, with no effects in BRAF(WT)-pericytes. Vemurafenib also inhibited (~3-fold decrease) cell viability in vitro and in BRAF(WT/V600E)-positive thyroid MPC patient-derived xenograft (PDX) mice (n = 5 mice per group). We established the first BRAF(WT/V600E)-dependent thyroid MPC cell culture. Our findings identify BRAF(WT/V600E) as a novel genetic aberration in MPC pathogenesis and MPC-associated biomarkers and imply that anti-BRAF(V600E) agents may be useful adjuvant therapy in BRAF(WT/V600E)-MPC patients. Patients with BRAF(WT/V600E)-MPC should be closely followed because of the risk for multifocality/recurrence.

Abstract
Desmoplastic melanoma (DM) is a rare variant of melanoma. Most frequently, it seems as clinically ambiguous and histologically characterized by a poorly demarcated neoplasm composed of a proliferation of spindle melanocytes dispersed in a prominent collagenous stroma. It often represents a diagnostic challenge, delaying its detection. We analyzed the expression profile of 29 (28 "pure" and 1 "combined") DM. These data were compared with a series of 62 primary vertical growth phase nondesmoplastic melanomas (NDMs) using a set of proteins including melanocytic markers (S-100 protein and melan-A) and epithelial-mesenchymal transition (EMT)-related proteins (E-cadherin, N-cadherin, SPARC, WT1, and PKCα). The S-100 protein confirmed the melanocytic origin of the DM (positive in 96%). The significant positive expression of N-cadherin, SPARC, and WT1 in DM (61%, 82%, and 71%) compared with NDM (28%, 43%, and 47%; P < 0.05) and a lower expression of E-cadherin in DM (14%) compared with NDM (61%) support specific adhesive and migratory properties of DM tumor cells. The study was carried out with tissue microarrays that partly limited the study of the tumor sections. This study demonstrates, for the first time, a prominent expression of epithelial-mesenchymal transition-related proteins in DMs and tries to be one more step in refining its knowledge and leading to a better understanding of its biological and clinical behaviors.

Abstract
BACKGROUND A few series addressing the cutaneous side effects related to imatinib in the skin have been published, but only one described scarce histopathologic information in seven patients. OBJECTIVE To characterize these lesions and compare the number of melanocytes between hypopigmented lesions and normal appearing skin. METHODS We retrieved clinical data of the patients and performed 24 skin biopsies (13 from hypopigmented skin and 11 from normal-appearing skin) within a cohort of 41 patients with chronic myeloid leukemia treated with imatinib. We classified the biopsies into three patterns. RESULTS About 45% of patients presented with periocular hypopigmentation. Perifollicular fibrosis was observed in hypopigmented skin biopsies (76.9%) and in normal-appearing skin (45.5%). Epidermal melanin, as determined with Masson-Fontana staining, and melanocyte number, as evaluated with MiTF, Melan A and c-kit immunostains, were lower in hypopigmented skin. CONCLUSIONS Histopathologic study of hypopigmented macules demonstrates the presence of melanin with a statistically significant decrease in the number of melanocytes. Therefore, these findings differ from vitiligo, as melanocytes are present. Three histopathological patterns may be found, namely (a) perifollicular fibrosis, (b) lichen planopilaris-like and (c) apparently normal skin. One of the most striking histopathologic finding consisted of the presence of perifollicular fibrosis in both hypopigmented lesions and apparently normal skin.

Abstract
The dermatologic hallmark of a recently described BAP1-associated cancer susceptibility syndrome is a dome-shaped nevus with distinct clinicopathological features, first delineated by Wiesner and colleagues. Here we describe the leading histopathological criteria of Wiesner nevus. Wiesner nevus is composed of various nevomelanocytic populations all showing different degrees of atypia ranging from hyperchromatic nevus cell-like to large atypical epithelioid cells. Immunohistochemically, Wiesner nevus is BAP1 negative and VE1 positive.

Abstract
Merkel cell carcinoma (MCC) is one of the most aggressive cancers of the skin. RASSFs are a family of tumor suppressors that are frequently inactivated by promoter hypermethylation in various cancers. We studied CpG island promoter hypermethylation in MCC of RASSF2, RASSF5A, RASSF5C and RASSF10 by combined bisulfite restriction analysis (COBRA) in MCC samples and control tissue. We found RASSF2 to be methylated in three out of 43 (7%), RASSF5A in 17 out of 39 (44%, but also 43% in normal tissue), RASSF5C in two out of 26 (8%) and RASSF10 in 19 out of 84 (23%) of the cancer samples. No correlation between the methylation status of the analyzed RASSFs or between RASSF methylation and MCC characteristics (primary versus metastatic, Merkel cell polyoma virus infection, age, sex) was found. Our results show that RASSF2, RASSF5C and RASSF10 are aberrantly hypermethylated in MCC to a varying degree and this might contribute to Merkel cell carcinogenesis.

Abstract
Clear cell tumors of the skin are observed in a wide variety of benign and malignant conditions with different histogenesis, sharing the presence of cells with abundant clear cytoplasm. Herein, we report the clinicopathologic features of a healthy young patient affected by asymptomatic, eruptive and disseminated, benign clear cell dermal tumors since early infancy. Neither family history nor genetic testing and counseling provided further useful information. The lesions were mostly confined to the face and lower left extremity with pink teleangiectatic papules and small nodules. Over a 4-year period, a total of 16 different cutaneous lesions were biopsied and histopathologic and immunohistochemical studies carried out; an additional lesion was also removed for electron microscopy examination. Histopathology evidenced multiple perivascular growths of spindle to oval and round cells intermingled with clear/granular cells throughout the dermis, with prominent desmoplasia and numerous capillary-like vessels with focal hemangiopericytoma-like features. Immunohistochemical neoplastic cells were uniformly positive for h-caldesmon and focally smooth muscle α-actin and CD13 indicating myoid differentiation whereas the consistent diffuse cytoplasmic staining for lysosome antigen, such as CD68PG-M1 and NKI/C3 along with the ultrastructural findings supported the view of a lysosome-mediated apoptotic process. The differential diagnosis with other clear cell cutaneous neoplasms is discussed.

The genus Alternaria has more than 80 species. Alternaria alternata and Alternaria infectoria are the most frequent species associated with infections in humans. Their clinical importance lies in the growing number of cases reported in immunocompromised patients.

Abstract
AIMS To report on 15 cases of Merkel cell carcinoma (MCC) with divergent differentiation, to characterize its clinicopathological spectrum and its relationship with Merkel cell polyomavirus (MCV). METHODS AND RESULTS Fifteen patients with a mean age of 81 years were included. Follow-up was available for 13 cases (range 12 days to 6 years; median 6 months). Recurrence, metastasis and mortality rates were 15.4%, 53.8% and 61.5%, respectively. All tumours showed the typical histological and immunohistochemical features of MCC, with at least one additional divergent component. Eight cases had a single aberrant component (squamous in six cases, follicular in one case, and porocarcinoma in one case), six cases had two aberrant components (squamous and sarcomatous in three cases, glandular and squamous in two cases, and sarcomatous and neuroblastic in one case), and one case had three aberrant components (glandular, squamous, and sarcomatous). All cases had dysplastic changes in the overlying epithelium, and four of 15 showed epidermotropism. PCR analysis for Merkel cell polyomavirus (MCV) gave negative results in all 12 cases tested. CONCLUSIONS Merkel cell carcinoma with divergent differentiation is a highly aggressive tumour that might be difficult to recognize, owing to its wide histological variability. Negativity for MCV suggests that the virus is not implicated in the development of this subtype of MCC.

Abstract
Cytotoxic lymphomas comprise a spectrum of peripheral T-cell lymphomas that can have
a initial or late cutaneous presentation. We describe a 46-year-old man from Cape
Verde, with a dermatosis involving his face and trunk, consisting of monomorphic
papules with a smooth surface and both motor and sensory polyneuropathy.The
hypothesis of leprosy was supported by the clinical and initial hystopathological
findings and the patient was referred to our hospital with suspected Hansen's
disease. In the new skin and lymph node biopsies a lymphocyte population was
identified whose immunohystochemistry study allowed the diagnosis of T-cell lymphoma
with expression of cytotoxic markers. The patient was started on chemotherapy with
initial remission of the skin lesions but, subsequently, progression of systemic
disease.

Abstract
AIMS The family of perivascular epithelioid cell tumours (PEComas) comprises a related group of mesenchymal tumours of uncertain origin that show both smooth muscle and melanocytic differentiation markers. TFE3 nuclear immunoreactivity may be viewed as a supporting marker, as it has been found in a subset of visceral PEComas. We immunohistochemically analysed 17 cases of primary cutaneous PEComas for TFE3, and five of them also for SOX-10, and also analysed them by FISH for TFE3 rearrangement. METHODS AND RESULTS PEComas presented as skin-coloured tumours, in 12 women and five men, with a median age of 49.5 years. Tumours showed either a mixed clear cell-epithelioid cell pattern or a monomorphous clear cell pattern. None of the primary cutaneous PEComas showed detectable TFE3 or SOX-10 positivity. FISH assay for TFE3 rearrangement yielded negative results in all of the tested tumours. CONCLUSIONS Cutaneous PEComas are mostly composed of clear cells, and, unlike a subset of visceral and deep-seated PEComas, cutaneous PEComas consistently lack TFE3 expression. Owing to the lack of SOX-10 expression, a neural crest origin could not be shown.
