Inpatient dermatology is different in different countries. Compared with what has been described in the USA or UK, our data suggest an important surgical content of inpatient dermatology in Spain, not reported in those countries. Medical diagnoses also differ, consisting of more infections, and less psoriasis and dermatitis in our setting. Readmission rates are low when compared with previously published ones, a finding that supports a long-term benefit of hospitalization.
Pseudoangiosarcomatous, or pseudovascular, squamous cell carcinoma of skin is an unusual form of acantholytic (adenoid, pseudoglandular) squamous cell carcinoma that mimics the histolopathologic appearance of angiosarcoma. We report a case of pseudoangiosarcomatous squamous cell carcinoma arising adjacent to decubitus ulcers. The histopathologic examination of a wedge biopsy specimen revealed infiltrative cords of neoplastic cells that formed interanastomosing channels imitating angiosarcoma. Immunohistochemical staining was negative for the endothelial markers (CD31, CD34, and factor VIII-related antigen) and positive using cytokeratin antibodies (AE1/AE3 and 34 betaE12). Because of metastatic disease, palliative measures were undertaken and the patient died four months later. To our knowledge, our patient is the first with pseudoangiosarcomatous squamous cell carcinoma of skin developing within decubitus ulcer.
Melanoma incidence has increased dramatically over the last decades in most industrial countries, mainly as a result of the large numbers of early melanomas being diagnosed. Simultaneously, a lack of commensurate change in mortality has been reported, raising the possibility that skin melanoma may have modified its aggressiveness as a result of the increased diagnosis of biologically benign lesions. The main data and controversies arising from the melanoma epidemic are reviewed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
