RMH is a rare benign condition of the deep dermis and subcutaneous fat with only 22 cases existing in the English literature. To our knowledge, this is the first report of an elderly man presenting with RMH, presumptively present since birth. There was no evidence of cellular or malignant degeneration. While the etiology of RMH is unknown, possible explanations include aberrancy in the embryonic migration of mesodermally derived tissues or a genetic defect predisposing to the formation of hamartomas.
Miliaria profunda is an uncommon but highly characteristic disorder that can be disabling. We describe a patient with miliaria profunda who responded to therapy with anhydrous lanolin and isotretinoin. Clinical features, pathogenesis, differential diagnosis, and therapy are reviewed.
We present the clinicopathologic features of a case initially interpreted as lymphocytoma cutis that was later determined to be lymphoepithelioma-like carcinoma of the skin. The histologic presence of nodular aggregates of undifferentiated epithelioid cells surrounded by a dense, reactive lymphocytic infiltrate should prompt consideration of the diagnosis of lymphoepithelioma-like carcinoma of the skin. This lesion should be distinguished from lymphocytoma cutis, B-cell lymphoma, and cutaneous lymphadenoma.
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.
