Syringocystadenoma papilliferum (SCAP) is a benign tumor most commonly located on the head and neck area often associated with nevus sebaceus. In its usual location, the human papillomavirus (HPV) DNA and mutations in the RAS/mitogen-activated protein kinase signaling pathway have been detected in SCAP. We studied 16 cases of SCAP in the anogenital areas and buttock where this neoplasm is rare and attempted to find out whether SCAP in these sites have different histopathological and molecular biological features...

BACKGROUND: Recent reports indicate that tufted angioma is a rare vascular neoplasm that manifests more frequently at birth than previously thought. Few studies specifically address congenital presentation. OBJECTIVES: We analyzed the clinicopathological characteristics, clinical course, and treatment of congenital tufted angioma (cTA) and evaluated variables that were indicative of problematic lesions. METHODS: We performed an observational retrospective study of 30 patients with cTA in 9 Spanish hospitals over a 14-year period...

Cellular neurothekeoma (CNT) is a dermal lesion with still unknown histogenesis, characterized by immunohistochemical staining for NKI/C3, NSE, MiTF, CD10 and CD68, whereas S100 protein, desmin and cytokeratins are negative. Particularly, in several studies NKI/C3 has been reported as a strong marker of CNT. We describe herein the clinical, histopathological and immunohistochemical features of two cases morphologically consistent with myxoid CNT, one of which showing some atypical features, both characterized by negative immunohistochemical staining for NKI/C3...

Alveolar soft-part sarcoma is a rare neoplasm of unknown histogenesis that accounts for less than 1% of all soft-tissue sarcomas. The tumor is highly vascularized with small vascular spaces separating nests of cells, and from cytogenetic point of view, is characterized by chromosome rearrangement der(17)t(X:17)(p11:q25) that results in the ASPL-TFE3 translocation. It can occur at any age, but it is most common between 15 and 35 years of age. The prognosis is poor, despite the relatively slow growth of the tumor...

Despite new horizons opened by recent advances in molecular pathology, histological evaluation still remains the diagnostic gold standard regarding cutaneous melanocytic neoplasms. Several histological variants of melanoma have been described, and their knowledge is crucial for accurate diagnosis and classification of cases with unusual clinicopathological features. Uncommon histological variants of melanoma have been described based on a broad constellation of features, including architectural pattern, stromal alterations, cytological attributes, and other morphological properties...

Bone involvement is relatively rare in vascular malformations. Gorham-Stout disease, also referred to as vanishing bone disease , is characterized by osteoclast activation and osteolysis caused by proliferating lymphatic endothelial cells. We present the case of a 12-year-old boy who had Gorham-Stout disease at the age of 8 years. The clinical course was complicated by pathological fractures and localized intravascular consumption coagulopathy. Sclerotherapy and embolization therapy led to normalization of the coagulation parameters and significant improvement of the clinical findings...

Papular elastorrhexis, a rare defect of dermal elastic fibers of unknown origin, usually involves the trunk and extremities of children or young adults. We report the case of a 62-year-old woman with multiple soft, skin-colored facial papules with histological findings characteristic of papular elastorrhexis. Awareness of this entity may allow for its proper identification outside the usual clinical setting.

Sebaceous neoplasms with an organoid pattern (rippled, labyrinthine/sinusoidal, carcinoid-like, and petaloid) are rare. Previous studies suggested that the above patterns likely represent variations along a morphological continuum. The objectives of this study were to (1) validate this proposition by studying a large number of cases, (2) determine whether there are specific associations with clinical features, (3) establish their frequency, and (4) determine whether they have any association with Muir-Torre syndrome...

The association of junctional epidermolysis bullosa with pyloric atresia (JEB-PA) and aplasia cutis congenita (ACC) was described by El Shafie et al. (J Pediatr Surg 14(4):446-449, 1979) and Carmi et al. (Am J Med Genet 11:319-328, 1982). Most patients die in the first weeks of life, and no curative treatment options are available so far. We describe a patient with JEB-PA and ACC (OMIM # 226730) who was treated for extensive areas of ACC by Integra® -Dermal Regeneration Template and split-thickness skin grafting (STSG)...

BACKGROUND: We investigated 2 cases of deceptively bland cutaneous angiosarcoma (AS), which showed a uniform clinical presentation with a rapidly growing tumor on the nose. It remains unclear whether this was a primary cutaneous manifestation or a metastasis. Both tumors initially presented a high histologic overlap with a benign vascular tumor. The diagnosis was primarily based on the rapidly progressing clinical course and on the results of the staging procedures. METHODS: Immunohistochemical stains were performed for cytokeratin (AE1/AE3 and MNF116), CD31, ERG, CD34 (HPCA1/my10), D2-40/podoplanin, LYVE-1, Ki67, PHH3, αSMA (1A4), MYC, FOS-B, CAMTA-1, TFE-3, WT1, nestin, VEGFR-2(KDR), VEGFR-3(FLT4), HHV8...

Synovial sarcoma (SS) accounts for 5%-10% of all soft tissue sarcomas. It is a well-defined soft tissue neoplasm with biphasic and monophasic histologic subtypes and unknown histogenesis. It usually occurs in the extremities, especially the thigh-knee region of young adults. Recurrences are frequent and distant metastasis developed in approximately half of the patients. SSs are characterized by a recurrent nonrandom chromosomal translocation, t(X; 18) (p11; q11), which is considered the primary genetic event in more than 90% of cases...

BACKGROUND: Accurate distinction of epithelioid hemangioma (EH) from its malignant mimics is paramount but remains challenging due to its wide morphological spectrum and lack of objective molecular markers. FOSB oncogenic activation was recently identified as a key event in endothelial proliferation. We sought to investigate the FOSB staining pattern in EH with angiolymphoid hyperplasia with eosinophilia (EH-AHLE) morphology and to evaluate its value in differential diagnosis of epithelioid vascular tumors...

Nukleinsäure-Amplifikations-Techniken (NAT), wie die PCR, sind hochsensitiv sowie selektiv und stellen in der mikrobiologischen Diagnostik wertvolle Ergänzungen zur kulturellen Anzucht und Serologie dar. Sie bergen aber gerade bei formalinfixiertem und in Paraffin eingebettetem Gewebe ein Risiko für sowohl falsch negative als auch falsch positive Resultate, welches nicht immer richtig eingeschätzt wird. Daher haben Vertreter der Deutschen Gesellschaft für Hygiene und Mikrobiologie (DGHM) und der Deutschen Dermatologischen Gesellschaft (DDG) einen Konsensus in Form einer Übersichtsarbeit erarbeitet, wann eine NAT am Paraffinschnitt angezeigt und sinnvoll ist und welche Punkte dabei in der Präanalytik und Befundinterpretation beachtet werden müssen...

Nucleic acid amplification techniques (NATs), such as PCR, are highly sensitive and specific methods that have become valuable supplements to culture and serology in the diagnosis of infectious disorders. However, especially when using formalin-fixed and paraffin-embedded tissue, these techniques are associated with both false-negative and false-positive results, a pitfall that is frequently misjudged. Representatives of the German Society of Hygiene and Microbiology (DGHM) and the German Society of Dermatology (DDG) therefore set out to develop a consensus - in the form of a review article - on the appropriate indications for NATs using paraffin-embedded tissue, its contraindications, and the key points to be considered in the pre- and post-analytical phase...

Cutaneous manifestations secondary to paraprotein deposits in the skin include a group of different disorders that although rare, may be the first clinical manifestation of the underlying hematologic dyscrasia. In this article we review the clinical manifestations and histopathologic findings of the processes that result from specific deposition of the paraprotein in different structures of the skin. Paraneoplastic processes frequently associated with hematologic malignancies will not be covered in this review...

Erythema elevatum diutinum is a rare neutrophilic dermatoses with vasculitis, which presents as persistent, symmetrical, purple or brownish papules and nodules, mainly in the extensor surface of the limbs. We describe a case of erythema elevatum diutinum and polyarthritis as initial manifestations of Crohn's disease associated spondyloarthritis. A 51-year-old man, from São Tomé e Príncipe, with previous history of treated tuberculosis and chronic hepatitis B infection, was admitted due to 4 months history of polyarthritis, hyperpigmented papules on the extensor surfaces, occasional episodes of bloody mucous diarrhea and significant weight loss...

Spindle cell hemangioma (SCH) is a distinct vascular soft-tissue lesion characterized by cavernous blood vessels and a spindle cell component mainly occurring in the distal extremities of young adults. The majority of cases harbor heterozygous mutations in IDH1/2 sporadically or rarely in association with Maffucci syndrome. However, based on mosaicism and accordingly a low percentage of lesional cells harboring a mutant allele, detection can be challenging. We tested 19 sporadic SCHs by Sanger sequencing, multiplex ligation-dependent probe amplification (MLPA), conventional next generation sequencing (NGS), and NGS using a single molecule molecular inversion probes (smMIP)-based library preparation to compare their diagnostic value...

Human parvovirus B19 (B19V) causes a number of skin exanthemas and has been related to both cutaneous and systemic diseases. Tropism of the virus for the rapidly proliferating erythroid progenitor cells in the bone marrow and fetal liver explains the pathogenesis of anemia and fetal hydrops. The cutaneous lesions of erythema infectiosum and other B19V-related exanthemas have been attributed to the deposition of immune complexes in the skin. We report on the immunohistochemical detection of B19V protein in the cytoplasm of dermal endothelial cells in a case of periflexural exanthema in a 28-year-old woman...
