“…Ultrasound evaluation of the mass generally reveals a smooth, lobulated mass in the superficial subcutaneous tissue. 4 The mass appears hypoechoic and often has increased vascularity. The classic MRI appearance is a T1-hypointense, T2-hyperintense mass, with homogeneous enhancement after contrast administration.…”

BACKGROUND Benign eccrine spiradenoma is a rare tumor arising from the sweat glands and is a pathology that is almost never encountered in routine neurosurgical practice. Although this is a rare pathology, it is one that should be included in the differential diagnosis for a patient presenting with a painful, subcutaneous mass, because it can guide further treatment considerations. OBSERVATIONS The authors present a case of benign eccrine spiradenoma that mimicked a nerve sheath tumor in clinical presentation, imaging characteristics, and gross appearance. LESSONS Complete local excision of these lesions is the gold standard treatment, because they are painful, and there are reports of local recurrence and malignant degeneration with incomplete resection. For this reason, neurosurgeons should be sure to include this in the differential diagnosis of a patient with a painful, subcutaneous mass, because it may help to guide management decisions.

“…ES are small in size usually measuring 2-3 cm, however variable size range from 1 to 10 cm has been reported in literature. 2,4,5 On color Doppler, low resistance color flow may be seen in both periphery and central portion. On MRI, the mass demonstrates low signal intensity on T1 weighted images and intermediate to high signal intensity on T2 or short tau inversion recovery (STIR) weighted images.…”

“…3,4 In the existing literature, only a few studies have described the imaging features of ES. 2,5 Case Report A 32-year-old male presented to the orthopedic clinic with gradually progressive painful swelling on the medial plantar surface of midfoot. The patient reported that this lesion had been present for 3 years; however both pain and swelling had progressively increased over approximately 10 weeks prompting him to seek medical attention.…”

Eccrine spiradenoma (ES) is a rare benign tumor of the eccrine sweat gland typically located in the dermis and subcutaneous layers of the skin. Recent literature suggests they typically arise from proximal torso and upper extremities and commonly present as painful subcutaneous nodules. Given its scarcity, imaging findings are not well established. We report an interesting case of plantar eccrine spiradenoma describing its imaging features and closest differentials.

“…Recent reports have emphasized the role of ultrasound in the diagnosis of eccrine spiradenoma 2 , 6 , 7 . Jin et al 6 reported a case of an eccrine spiradenoma and compared its ultrasound features with those of other sweat gland tumors in previous literature.…”

Giant vascular eccrine spiradenoma presenting as a thrombosed varix

Eccrine spiradenoma is a benign adnexal tumor of the sweat gland. Giant vascular eccrine spiradenoma is a rare variant of eccrine spiradenoma, characterized by its large size and florid vascularity. Its rarity and clinical appearance give rise to typical misdiagnosis as angiomatous lesions. We present a case of a giant vascular eccrine spiradenoma that was initially diagnosed as a thrombosed varix on the basis of clinical presentation and ultrasound features. This case reintroduces this rare condition and also highlights the differential diagnoses of lower limb skin nodules that may masquerade as a thrombosed varix.
