Is aggressive digital papillary adenocarcinoma (ADPA) really aggressive? Does it only occur at digital location? Does it always have microscopic papillary features? Is it really adenocarcinoma? Let’s us address these questions one by one. Is ADPA aggressive? From the term, namely, aggressive digital papillary adenocarcinoma, one would interpret this as high(More)
Dermatopathology represents the gold standard for the diagnosis of skin diseases and neoplasms that cannot be diagnosed on clinical grounds alone. The aim of this study was to test the feasibility and to assess the accuracy of an Internet-based real-time (live) teledermatopathology consultation. Twenty teaching cases and 10 randomly selected routine cases(More)
In general, epithelial neoplasm can be classified into three categories, namely, benign neoplasm, carcinoma in situ (noninvasive carcinoma) and invasive carcinoma. When the term carcinoma used unmodified, it generally refers to invasive carcinoma. However, since the introduction of the concept of carcinoma in situ by Broder in 1932 [1], there have been only(More)
Although carcinoma in situ has been accepted as a well-established concept and diagnostic category, for reasons unknown sebaceous carcinoma in situ has not been recognized yet in general pathology or dermatopathology. Such lesions have always been misinterpreted as either benign neoplasm or sebaceous carcinoma. In the present essay, we provide a convincing(More)
The authors present a first case of pigmented perivascular epithelioid cell tumor (PEComa) of the skin, which was misdiagnosed histopathologically as metastatic melanoma. PEComa are exceedingly rare neoplasms, and only a few cases have been reported in kidney, liver, and pelvis. Herein, we describe this very rare entity in the subcutaneous tissue of the(More)
To the Editor, Wu et al recently reported an interesting case entitled “Papillary adnexal neoplasm (aggressive digital papillary adenocarcinoma) on the ankle of a 15-year-old girl: case report and review of literature from a pediatric perspective” in the Journal of Cutaneous Pathology. There are 2 points worthy of commenting, in our opinion. First of all,(More)
Primary effusion lymphoma (PEL) or body cavity lymphoma is a rare type of extra nodal lymphoma of B-cell origin that presents as lymphomatous effusion(s) without any nodal enlargement or tumor masses. It belongs to the group of AIDS related non-Hodgkin's lymphomas. First described in 1996 in HIV infected individuals who were coinfected with Kaposi's(More)
We investigated the feasibility and diagnostic agreement of a virtual slide system (VSS) in teledermatopathology. Forty-six biopsy specimens from inflammatory skin diseases were selected and scanned with a VSS at the Research Unit of Teledermatology, Medical University of Graz, Graz, Austria. Images were stored on a virtual slide server on which a specific(More)
A 46‑year‑old obese male with a medical history of thalassemia minor presented to the emergency room with complaints of severe fatigue and jaundice worsening over two weeks. On further evaluation, the patient was found to have significant hyperbilirubinemia and transaminitis. The hospital course was further complicated by pancytopenia requiring multiple(More)
Although rare isolated cases of adenocarcinoma in situ of skin have been reported in the literature, adenocarcinoma in situ of skin as a concept and as a diagnostic category has not been established in the field of dermatopathology. In this work, four cases of papillary adenocarcinoma in situ of the skin are presented. In addition, the notion that lesions(More)
