S047- Glomus Tumors: Diagnosis and Treatment

The presentation discusses glomus tumors, which are rare benign tumors accounting for 1 to 4% of all hand tumors, with a significant prevalence in the subungual area. Highlighting a study conducted in Casablanca from 2006 to 2023, it was found that glomus tumors represented 1.34% of outpatient consultations, particularly as the most common benign nail tumor following exhaustosis. The majority of patients were female, averaging 40 years in age, and often experienced severe paroxysmal pain, leading to misdiagnosis and psychiatric referrals prior to proper consultation. The tumor's clinical presentation includes specific characteristics like bluish-red discoloration and tenderness. Diagnosis is confirmed through the Lofpin test and may be supported by onychoscopy and imaging techniques, although smaller tumors can be overlooked. Surgical excision using a transangial approach is the preferred treatment, providing effective relief and functional outcomes with low recurrence rates. The presentation emphasizes that a high suspicion of glomus tumors should exist when patients present with severe pain and cold sensitivity in digits, and outlines the importance of proper diagnostic tests and surgical methods for ensuring successful treatment.
