Hidradenomas are benign tumors of the sweat glands that are rarely reported in childhood. The presence of mucinous change in hidradenomas, which consists of variable numbers of mucin-rich goblet cells, is occasionally observed in some adult clinical practices. However, it has not been previously reported in the pediatric population. Herein, we present a unique case of a mucinous hidradenoma presenting on the thigh of a 3-year old boy. The clinical presentation and histological features of the case, along with a literature review of published case reports of pediatric hidradenomas are described...

INTRODUCTION: Frontal fibrosing alopecia (FFA) is a cicatricial alopecia typically occurring in post-menopausal women. The etiology and pathophysiology of FFA is poorly understood but thought to be immune mediated. This study aims to further explore the extent of fibrosis and the inflammatory microenvironment by characterizing Langerhans cells (LCs), helper T cells, cytotoxic T cells, and B cells near hair follicles in FFA. METHODS: 11 paraffin-embedded tissues from patients with a clinical and histopathologic diagnosis of FFA were selected for immunohistochemical studies using CD3, CD4, CD8, CD1a, and CD20...

Carcinoma erysipeloides (CE) is a rare but distinctive form of cutaneous metastasis that clinically resembles erysipelas. Herein, we report a case of CE as the presenting feature of recurrent urothelial carcinoma.

Nevus sebaceus of Jadassohn, a congenital cutaneous hamartoma, has the potential to develop into various epidermal adnexal-origin neoplasms. While the most common neoplasms are trichoblastoma or syringocystadenoma, proliferating trichilemmal cysts are exceptionally rare. We report a case of a 63-year-old Cuban male with a giant proliferating trichilemmal cyst arising from a nevus sebaceus on the right shoulder which had been growing for 30 years. Proliferating trichilemmal cysts arising from nevus sebaceus cases are difficult to diagnose clinically and histologically since they are very rare and have not been defined by exact diagnostic criteria...

BACKGROUND: Well-differentiated neuroendocrine tumors (WDNETs) in skin include metastases from visceral primary sites and very uncommonly, primary cutaneous carcinoid tumors. Cutaneous WDNET may present a diagnostic challenge and in particular can be mistaken for a benign skin adnexal tumor. In contrast to cutaneous adnexal tumors, metastatic adenocarcinomas to the skin are cytokeratin 5/6 (CK 5/6) and p63 negative in the majority of cases. It is unclear if failure to stain with CK 5/6 and p63 would be helpful in differentiating WDNETs from cutaneous adnexal neoplasms...

Desmoplastic melanoma (DM) and cutaneous malignant peripheral nerve sheath tumors (MPNST) reveal histological and immunohistochemical similarities, including S100 positivity and negative staining for conventional melanocytic markers. We present three cases of cutaneous S100-positive spindle cell tumors in elderly patients, in which first findings led to initial misdiagnoses as cutaneous MPNST and benign peripheral sheath nerve tumor (neurofibroma). The identification of adjacent atypical melanocytic hyperplasia in the overlying skin along with tumor cell proliferation, also in the superficial dermis, the neurotropic component and the absence of any relationship between the tumor and a major nerve, pre-existing neural benign tumor or the existence of stigmata suggestive of neurofibromatosis raised consideration of a desmoplastic melanoma...

BACKGROUND: Basal cell carcinoma (BCC) can resemble Merkel cell carcinoma (MCC) on histopathological examination and while CK20 is a useful marker in this differential, it is occasionally negative in MCC. CD56, a sensitive marker of neuroendocrine differentiation, is sometimes used to identify MCC, but has been reportedly variably positive in BCC as well. In contrast, CK5/6 consistently labels BCC but is not expressed in neuroendocrine tumors. METHODS: We evaluated twenty cases of BCC for the pattern of CD56 and cytokeratin 5/6 (CK5/6) staining, hypothesizing that these two stains could differentiate BCC from MCC in difficult cases...

Morphea (localized scleroderma) and eosinophilic fasciitis (EF) are rare fibrosing disorders which may present a diagnostic challenge. While histopathologic features are often distinct, in some cases there may be overlap. T-cells contribute to etiopathogenesis of both autoimmune conditions. We sought to determine whether T-cell immune polarization enables histopathologic distinction. We retrospectively examined clinicopathologically confirmed cases of morphea (n = 12) and EF (n = 8) using immunohistochemistry for CD3, CD8, and dual staining for CD4 with T-bet, GATA-3, STAT-3, or BNC-2 (transcription factors reported to be specific and mutually exclusive for Th1, Th2, Th17 and Th22 cells, respectively) to characterize the T-cell infiltrate...

BACKGROUND: Clear cell hidradenoma and cutaneous clear cell renal cell carcinoma (CCRCC) overlap morphologically. The distinction may be difficult in a patient with a history of CCRCC, presenting with a cutaneous nodule, potentially leading to an erroneous diagnosis. We investigated the usefulness of napsin A and paired box gene 8 (PAX-8) with previously studied markers epithelial membrane antigen (EMA), carcinoembryonic antigen (CEA), vimentin and CD 10 in differentiating CCRCC from hidradenoma...

BACKGROUND: So called "acquired elastotic hemangioma" (AEH) represents a peculiar vascular lesion affecting the sun-damaged skin of the extensor surface of the forearms or the lateral aspect of the neck of middle-aged or elderly women. METHODS: This is a clinicopathological and immunohistochemical study of a series of 6 lesions located on the knee or elbow showing epithelial features of lichen simplex chronicus (LSC)/prurigo nodularis (PN) with a marked subepidermal vascular proliferation closely resembling AEH...

Cutaneous manifestations of Waldenström macroglobulinemia may occur due to several mechanisms, the least common being direct skin infiltration by neoplastic cells. We report a case of patient that after 4-year history of indolent Waldenström macroglobulinemia developed skin infiltration by lymphoplasmacytoid cells in the form of a small, mildly indurated plaque on the anterior chest. MYD88 L265P mutation was detected both in the previous bone marrow biopsy and in the cutaneous lesion. We review the impact of this new genetic tool in the diagnosis and treatment of lymphoplasmacytic proliferations...

A 20 year-old male presented with multiple subcutaneous nodules on the head, neck, chest and oral cavity. FNA and biopsy showed pigmented fungal hyphae diagnostic of multifocal phaeohyphomycosis, found to be Exophiala spinifera by molecular diagnostics. The presentation initially raised concern for disseminated disease and occult immunosuppression. However, the patient appeared to be immunocompetent and otherwise healthy. Upon further inquiry, the patient was in a motor vehicle accident four years before presentation; he was ejected into a vegetable field resulting in multiple open wounds...

Skin diseases presenting with keratotic papules, atrophy, cicatricial alopecia, and/or "lichenoid" histopathologic changes have been described under at least 30 names. This family of diseases contains two subgroups, largely based on clinical features: keratosis pilaris atrophicans (KPA; including keratosis pilaris atrophicans faciei/ulerythema ophryogenes, atrophoderma vermiculata , and keratosis follicularis spinulosa decalvans); and the lichen planopilaris (LPP) subgroup (including LPP, frontal fibrosing alopecia, Graham-Little-Piccardi-Lassueur Syndrome, and fibrosing alopecia in a pattern distribution)...

BACKGROUND: SOX10 is a newer Schwannian and melanocytic marker that has generated great interest for its relative sensitivity and specificity in the diagnosis of neural crest-derived tumors. Previous studies with SOX10 have shown positive immunohistochemical expression in cutaneous eccrine glands and negative expression in eccrine ducts, apocrine glands and hair follicles. Thus, we hypothesized that some sweat gland tumors of presumed eccrine origin would be positive for SOX10, whereas apocrine-derived sweat gland tumors would not...

Adult-onset Still disease (AOSD) is a rare autoinflammatory syndrome characterized by recurring fevers, arthralgia, and consistent laboratory abnormalities that include leukocytosis and hyperferritinemia. Skin findings accompany the disease in nearly 90% of the cases. Early reports described evanescent, pruritic, salmon-pink or urticarial lesions, referred to as the typical eruption of AOSD. Histopathologic findings consist of superficial perivascular dermatitis with varying number of interstitial neutrophils...
