Ultrasonographic diagnosis of nodular hidradenoma

Clear Cell Hidradenoma: Characteristic Imaging Features on Ultrasonography, Computed Tomography, and Magnetic Resonance Imaging

“…Clear cell hidradenoma is classified as a cutaneous tumor originating from skin appendages. However, all of the clear cell hidradenomas in our study were primarily located in the subcutaneous fat layer with or without involvement of the dermal layer and were similar to those in previously published reports . This finding could be attributed to the relatively strong and elastic nature of the dermal layer compared with that of the subcutaneous fat layer, as was another sweat gland tumor reported by Jin et al Furthermore, there was no extension of the lesion to the epidermis or muscular structures in any case.…”

“…These small but palpable superficial lesions rarely require radiologic evaluation and are most often diagnosed and treated by excision. There are few reports on the findings of clear cell hidradenoma on ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI) . The purpose of this retrospective study was to analyze and describe the imaging features of clear cell hidradenoma seen on US, CT, and MRI.…”

Top Advances in Dermatologic Ultrasound

“…Some of these tumors can show mild vascularity in the periphery (Figure 7). 37,38,[51][52][53][54][55] Nevus Sebaceous of Jadassohn This is a congenital hamartoma characterized by an erythematous or yellowish patch, most commonly color Doppler) present a round-shaped mixed echogenicity hypodermal structure that protrudes into the dermis. There are anechoic and hypoechoic areas with pseudopolypoid structures that predominate in the borders.…”

Sonographic Characteristics of Apocrine Nodular Hidradenoma of the Skin

“…The use of sonography has been reported in hidradenoma as case reports with 1 or 2 cases . Mostly, these showed hidradenomas with the eccrine differentiation, and in most cases, the examinations were performed without following the guidelines and technical considerations for studying dermatologic lesions .…”
