Ultrasound Morphologic Features of Steatocystoma Multiplex With Clinical Correlation

Abstract

The ultrasound features of 87 steatocytoma multiplex (SCM) lesions detected in 9 patients are reported. Steatocytoma multiplex is a hamartomatous condition derived from the pilosebaceous duct junction that generates multiple cutaneous cystic lesions. It appeared as clusters of well-defined hypoechoic nodules with mild posterior enhancement in 100% of cases, with both dermal and subcutaneous locations in 67%. No calcification foci were detected within or at the periphery of the lesions. Fifty-six percent of the cases showed signs of hypervascularity in the edge of the nodules, and 44% of the lesions were associated with another dermatologic condition, most frequent being hidradenitis suppurativa (75%), followed by vellus hair cysts (25%). Steatocytoma multiplex shows ultrasound features that allow discrimination from other common cutaneous entities.

Cystic Presentation of High-Grade Ductal Carcinoma In Situ in an Inframammary Accessory Nipple

“…Upon review of the ultrasound, concerns were raised by dermatology A A B B that the mass was more likely an epidermal inclusion cyst with rupture given the more superficial and sac-free nature of sebaceous cysts, which commonly are associated with steatocystoma multiplex. 13 Definitive diagnosis of ductal carcinoma in situ was made with dermatopathologic examination. Prophylactic surgical excision of ABT has been recommended, suggesting that excisional biopsy and histopathologic examination is the more appropriate method to rule out malignancy.…”

Oral Steatocystoma Simplex—A Rare Tumor

“…1,2 The lesion has been described as hamartomatous malformations of the pilosebaceous duct junction (hair follicle unit). 3,4 It is classified into 2 groups: steatocystoma simplex (SS) and steatocystoma multiplex. Steatocystoma simplex presents as a solitary, noninherited tumor that affects adults and shows equal sex predilection.…”
