Multiple acquired smooth muscle hamartomas with thick-walled blood vessels on scalp.

Smooth muscle hamartoma (SMH) is a benign hamartomatous condition that consists of a dermal proliferation of smooth muscle cells. We hereby report a case of multiple, acquired SMHs on scalp. A 25-year-old male had a 6-year history of multiple, asymptomatic, hyperpigmented plaques on the scalp which were progressively increasing in number and size. Histopathological examination revealed large thick-walled blood vessels, in addition to the haphazardly arranged discrete smooth muscle bundles in the reticular dermis. This case of SMH is unusual in being acquired, having multiple lesions, involving scalp, and having thick-walled blood vessels apart from arrector pili muscle bundles. It emphasizes the wide spectrum of clinical and histopathological variations that may be associated with acquired SMH.

Epitheloid hemangioma: a report of two cases.

We report two cases of epitheloid hemangioma presented with multiple nodular lesions over head and neck region. One of them gave history of bleeding on minor trauma. Pyogenic granuloma was considered as a differential diagnosis from the morphological appearance and history of bleeding. Nodular leprosy, sarcoidosis, and secondary syphilis were also considered. Histopathological examination of both was typical of epitheloid hemangioma, an entity commonly overlooked clinically due to its rarity.

Gorlin syndrome.

Gorlin Syndrome, a rare genodermatosis, otherwise known as Nevoid basal cell carcinoma syndrome (NBCCS) is a multisystem disease affecting skin, nervous system, eyes, endocrine glands, and bones. It is characterized by multiple basal cell carcinomas, palmoplantar pits, jaw cysts, and bony deformities like kyphoscoliosis and frontal bossing. We would like to report a case of Gorlin syndrome with classical features, as this is a rare genodermatosis.
