“…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. 9,10 They usually demonstrate homogenous enhancement on contrast imaging. Giant vascular ES with florid vascularity appearance has been described showing hemorrhagic features.…”

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.

“…The main MR imaging feature of an angiolipoma is presence of a fatty tumor 11 , while schwannomas show a target sign in 90% of lesions 12 . Neuromas, glomus tumors, eccrine spiradenomas, and synovial sarcomas show non-specific, low-signal intensities on T1-weighted images and high-signal intensities on T2-weighted images [13][14][15] .…”

Background: Angioleiomyomas are usually small and relatively rare painful soft tissue tumors, and are usually less than 2 cm in diameter. Magnetic resonance (MR) imaging features of typical angioleiomyomas are not well understood, and their association with histologic subtypes is not clear. In the present study, MR images of average sized angioleiomyomas were compared with regard to specific histologic subtypes. Methods: We performed a retrospective review of medical records, MR imaging data, and histologic specimens of 18 consecutive patients with angioleiomyomas that were extirpated at our hospital between January 2006 and December 2013. Results: Most of the lesions showed homogenous iso-signal intensities compared to skeletal muscle on T1-weighted images; however, on T2-weighted images, solid and venous types showed heterogenous and iso-to slightly high-signal intensity, while the cavernous type showed high-signal intensity. Most of the lesions had a low-signal intensity rim, and two thirds of them had adjacent vessels. Conclusions: Our results suggested that MR findings of angioleiomyoma vary depending on histologic subtypes. T2-weighted images of solid and venous types of angioleiomyoma show specific MR findings which allow for differentiation from other soft tissue tumors such as soft tissue sarcomas. These mostly show iso-to slightly high-signal intensity compared to skeletal muscle, while the cavernous type show non-specific findings. Thus, solid and venous types of angioleiomyoma could be diagnosed preoperatively via clinical findings and MR imaging.

“…Bleeding and internal hemorrhage are common presentations and give rise to the frequent misdiagnosis of GVES as angiomatous lesions 9 . Aydin et al 10 reported a case of GVES presenting as a painful nodule on the anterolateral leg of a middle-aged man. Magnetic resonance imaging (MRI) showed a well-defined subcutaneous mass with hypointensity on T1-weighted images and hyperintensity with internal separations on T2-weighted images.…”

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.
