Successful treatment of generalized elastolytic giant cell granuloma with psoralen-ultraviolet A.

Elastolytic giant cell granuloma (EGCG) is an infrequent granulomatous skin disorder with variable response to different therapeutic regimens. Information on the benefit of phototherapy is very scarce as this therapy has seldom been tried in the affected patients. We present the results achieved in two female patients after undergoing psoralen-ultraviolet A (PUVA). Two 54-year-old otherwise healthy female patients received a course of PUVA after trying other alternatives. Complete clearance was achieved in the two patients with excellent tolerance and no adverse effects. We consider PUVA is a well-tolerated, safe, and effective treatment for patients with EGCG.

Multiple congenital familial smooth muscle hamartoma in two siblings.

Smooth muscle hamartoma (SMH) is a cutaneous malformation mainly composed of a disorganized proliferation of normal muscle fibers that arise from arrector pili. It usually presents as a single congenital lesion that frequently involves the back and the lower limbs. Unusual clinical presentations, such as atypical localizations, multiple disseminated lesions, and generalized forms have been rarely described. In 2001, Gualandri et al. reported the presence of multiple SMH in three members of the same family, namely two brothers and their mother. This is, as far as we know, the only familial case reported in the English literature. We herein describe a similar case affecting two siblings who presented with identical congenital lesions in the same location.

Coexistence of two types of clinical lesions in childhood-onset mastocytosis.

The vast majority of mastocytosis appear in childhood, urticaria pigmentosa (UP) and mastocytomas being the most common types. Terms such as "xanthelasmoid mastocytosis", "pseudoxanthomatous mastocytosis" or "nodular mastocytosis" have been introduced in the literature to describe the presence of yellowish papular or nodular lesions. We describe two children with cutaneous mastocytosis showing yellowish lesions in combination with other skin lesions. A 10-year-old girl presented with asymptomatic lesions in her vulva at birth, and developed brownish macules on her trunk years after. An eight-year-old boy presented with multiple yellowish papular lesions on his trunk, neck and limbs coexisting with a few clinically anetodermic lesions. No systemic involvement was found and the skin biopsy confirmed a cutaneous mastocytosis in both cases. The two patients are currently asymptomatic and are being periodically followed up. Mastocytoses may show a variety of clinical lesions, sometimes leading to misdiagnosis. Although there are previous reports, involvement of the mucosae and secondary anetoderma are not common findings in cutaneous mastocytoses. We consider that cutaneous manifestations of mastocytoses compose a clinical spectrum, thus explaining the coexistence of different clinical lesions and the development of uncommon presentations.

Friction induced skin tags.

Skin tags are common benign neoplasm located predominantly in intertriginous skin. Generally of cosmetic concern, they can be easily treated with cryotherapy, electrodessication or snip-excision. Despite their high incidence data about their etiopathogenesis are scarce in the medical literature. We describe a patient who developed multiple skin tags arranged in a linear fashion suggesting an etiopathogenic role for friction.
