Glomeruloid Hemangioma as a Late Manifestation of POEMS Syndrome.

Glomeruloid hemangiomas were first described by Chan in 1990 as a cutaneous marker of POEMS syndrome (Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal proteinemia, and Skin changes). POEMS syndrome is a multisystem disease with a significant cutaneous involvement. Among its manifestations, hemangiomas are common, observed in up to one third of the patients, and, although specific, the glomeruloid subtype is very rare. The vascular endothelium growth factor (VEGF) is an angiogenic stimulation factor, which also induces increased systemic vascular permeability. Thus, a scenario of overexpression of VEGF can credibly lead to the assumption of an association between cutaneous hemangiomas and systemic manifestations, implying prognostic and therapeutic considerations and reinforcing the importance of dermatological periodical consultations for these patients. We report the case of a patient in whom glomeruloid hemangiomas marked the recurrence of POEMS syndrome, occurring before the systemic symptoms.

Primary isolated osteoma cutis of the face.

We report a healthy, 44-year-old woman presenting with an at least a 20-year history of hardened papules in the forehead region, extending to the scalp. The biopsy and histopathologic exam confirmed a diagnosis of osteoma cutis. We review the literature review and discuss the classification of the cutaneous ossification process presented, along with the results of the surgical treatment.
