“…Only two cases of CSMH and none of ASMH on scalp have been reported so far. Günlemez et al reported a case of CSMH of scalp in an 8‐day‐old male infant who presented with a hyperpigmented, slightly elevated plaque with abundant, dark hairs confined to the whole scalp, which on histopathological examination showed features of SMH . Knable and Treadwell documented a 7‐week‐old white boy with a pigmented, hypertrichotic nodule on the scalp since birth, which was diagnosed as CSMH …”

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.

“…Smooth muscle hamartoma (SMH) presents as a firm, skin‐colored to lightly pigmented patch or plaque, mainly located on the trunk or proximal extremities, with the lumbosacral area being the most commonly affected. SMH affecting the scalp has been rarely reported (Günlemez et al, ). Follicular prominence, perifollicular papules, or hypertrichosis can be present within the SMH.…”

Terminal osseous dysplasia with pigmentary defects (TODPD; MIM #300244) is an extremely rare, X-linked dominant, in utero male-lethal disease, characterized by skeletal dysplasia of the limbs, pigmentary defects of the skin, and recurrent digital fibromatosis of childhood. Delayed/ abnormal ossification of bones of the hands and feet, joint contractures, and dysmorphic facial features may accompany. A single recurrent mutation (c.5217 G>A) of the FLNA gene which causes cryptic splicing was identified as the cause of the disease. We here present the first TODPD case from Turkey with full-blown phenotype who exhibit unique additional findings, hypopigmented patch on the lower extremity following Blaschko's lines and smooth muscle hamartoma of the scalp in review of all the previously reported TODPD cases.
