Subungual Exostosis: High-Resolution Ultrasound Findings

2019 , WHITTLE, CAROLINA , Javiera Aguirre , Veronica Catalán , Fabiola Vargas , FAJRE WIPE, XIMENA ELIZABETH

Subungual exostosis is a rare solitary benign osteocartilaginous tumor that arises from the tuft of the distal phalanx beneath the nail. Because of its multiple clinical presentations, it is commonly underdiagnosed, resulting in delayed diagnosis and inadequate treatment. This report provides results from a 6-year retrospective study. All patients with a sonographic diagnosis of subungual exostosis confirmed surgically were selected. The data came from a series of 19 patient cases. Only 15.7% were clinically suspected. The median age was 21 years, and 63% were females. The sonographic findings were nail dystrophy, distal onycholysis, abnormal nail incurvation, subungual space enlargement, and the presence of hyperechogenic subungual image with acoustic shadowing that continued until the phalanx surface. Sonography provides an excellent diagnostic method for subungual exostosis, with findings that are pathognomonic.

Herniated superficial lipomas in gluteal and thigh support areas: a special clinical ultrasound presentation

2022 , WHITTLE, CAROLINA , FAJRE WIPE, XIMENA ELIZABETH , Catalina Silva , CASTRO MENDEZ, ALEX

Background Lipomas are the most frequent benign tumor. They have been described as soft, well-defined, slow-growing palpable masses, and classified as deep or superficial. Purpose To present the clinical and ultrasound findings of herniated superficial subcutaneous lipoma (HSL), located in pressure/support areas, not previously described. Material and Methods A seven-year retrospective review was performed. Patients with a preoperative high-resolution ultrasound (HRUS) diagnosis of HSL archived in the computational system and histological study information were selected. Results A total of 37 patients (mean age = 46 years) were recruited. The clinical diagnoses were “lipoma” or “suspected lipoma” in just 46% of the cases. This was three times more frequent in women. Tumors were located mainly in the gluteal (38%) and proximal thigh areas (35%). Clinically, all patients showed small, soft, rounded skin nodules. On HRUS, they appear as lipomatous tumors that protruded, compressed, and thinned the covering dermal layer. The subcutaneous portion was bigger than the herniated part, with an iceberg image. Conclusion HSL in support areas have a special clinical ultrasound presentation, not previously described. It is important to recognize them for a proper diagnosis and treatment, especially because they clinically may present as small superficial lesions; however, they are associated with a larger subcutaneous portion (iceberg image). It is probable that an estrogen influence on the adipose tissue can be suspected because of the female predominance.
