“…To our knowledge, steatocystoma multiplex, a rare autosomal dominant disorder in which numerous steatocystomas, pathologically resembling sebaceous cysts, develop in the skin of the anterior chest and axilla, has not been reported at breast MR imaging. However, it could conceivably manifest as multiple bilateral sebaceous cysts (40).…”

Although numerous studies have outlined the benefits of contrast material-enhanced magnetic resonance (MR) imaging for the detection of breast parenchymal findings, the assessment of lesions of the skin and superficial tissue at breast MR imaging has largely been overlooked. Such lesions, both benign and malignant, are commonly encountered at breast MR imaging, and their detection and diagnosis are often imperative. These lesions include superficial, locally extensive, inflammatory, and recurrent breast cancers; iatrogenic changes; sebaceous cysts; and less prevalent diseases such as granulomatous mastitis and angiosarcomas, among others. As MR imaging continues to be used with increasing frequency in both the screening and diagnostic settings, these lesions will be encountered more often; consequently, a better understanding of which lesions may be ignored and which require further evaluation will become increasingly important. Frequently, MR imaging alone may not clearly indicate the cause of lesions of the breast skin and superficial tissue. However, radiologists should thoroughly assess such lesions, taking into consideration the spectrum of possible causes. Mammography, ultrasonography, consultation with clinicians or dermatologists regarding physical examination findings, and, when necessary, correlation with pathologic findings in biopsy specimens may be used in conjunction with MR imaging to establish both the importance of these lesions and their definitive diagnoses.

Dear Editor, Steatocystoma, originating from nevoid malformations of the pilosebaceous duct junction, is classified into steatocystoma multiplex (SCM) and steatocystoma simplex (SCS). The clinical manifestations of SCM differ from those of SCS: SCS is a single lesion that usually develops on the head or neck, while SCM develops on the trunk or extremities and is often inherited as an autosomal dominant trait. Brownstein described 30 cases of SCS in 1982. 1 Eleven lesions were present on the face, and the others developed on the scalp, neck, back, chest and limbs. Although several cases of SCS have been reported since then, ultrasonic analysis of SCS was described only once by Sunohara et al. 2 Here, we describe and discuss sonographic findings in a patient with SCS.A 41-year-old man presented to our hospital with a soft subcutaneous nodule under his umbilicus. The tumor had been growing slowly for more than 1 year. Physical examination revealed a soft, well-defined tumor measuring 1 cm in diameter with a smooth surface (Fig. 1a). The patient's family history was unremarkable, and we could not find any other skin tumors. Ultrasonographically, the nodule was well circumscribed and exhibited heteroechogenicity with the lateral shadows; it was "doughnut" shaped, with a small hypoechoic cystic lesion in the center (Fig. 1b). When we divided the resected specimen in half, the cyst contained the serous fluid and the viscous contents (Fig. 1c). Histopathological examination revealed an empty cyst attached to sebaceous glands in the dermis. The cyst wall was composed of several layers of squamous epithelium and hyalinized eosinophilic cuticle in the inner epithelium surface (Fig. 1d,e). The differential diagnosis included epidermal cyst, vellus hair cyst and SCS. Epidermal cyst was excluded by adhesion of sebaceous gland. We excluded vellus hair cyst because the cyst included no vellus hair. Based on these findings, we diagnosed the tumor as SCS.Some case reports of SCM have been accompanied by the ultrasonographic findings. 3-5 Mester et al. reported a case of SCM with sonographic examination. They stated the lesions were well defined and hypoechoic, and some of them contained fluid-debris levels (i.e. because the oily component was hypoechoic and the keratinous debris was isoechoic, there was a fluid-debris level between these two materials). 3 Park et al. examined 18 SCM lesions in five women. Fifteen of the lesions were hypoechoic and the others were isoechoic. 4 Wan et al. described ultrasonic features of SMC associated with a 59-year-old woman. The patient had multiple small nodules on the chest wall, axillae and forearm. On ultrasonography, the nodules were hypoechoic, mixed echoic and isoechoic lesions with well-circumscribed margins. 5 Previous SCM case reports have not described the aforementioned "doughnut"-shaped features (hypoechoic lesion in the center of an isoechoic cyst) present in our patient. Sunohara et al. described two cases of SCS in 2-year-old and 4-monthold girls. Ultrasonography revealed a well-d...

“…The finding of a well circumscribed, round, fat density nodule on mammography or an intradermal hypoechoic nodule on sonography, combined with a family history and an extensive bilateral spatial distribution of the nodules, confirm the diagnosis of steatocystoma multiplex [12].…”

“…A lumen which is partly present in a few areas of the cord, is filled with the cellular debris of the keratinocytes, corneocytes, sebocytes, or the trapped hairs [4]. In comparison, the trichilemmal cysts take their origin from the outer root sheath of the follicle, the epidermal cysts take their origin from the infundibulum and the vellus hair shafts take their origin from the infundibuloisthmic junction or the isthmus [12].…”

A 17 years old female presented with multiple asymptomatic cutaneous cysts all over body, sparing the head and neck region. The microscopic examination of the cysts showed the features of steatocystoma multiplex. This disorder, although it is asymptomatic, is a cosmetic threat to the patient . Only a few cases of the patients with an autosomal dominant mutation, who had keratin 17, have been reported. We are reporting here, a case of steatocystoma multiplex in a 17 years old female, along with its review of literature.
