Recurrent lymphangiomatous lesion of the chest wall and axilla in a young female: a case report

Lymphangiomas are uncommon, benign lymphatic malformations predominantly identified in infancy, with adult presentations being exceedingly rare-particularly when involving the chest wall and axillary region. We report the case of a 20-year-old woman presenting with a painless, progressively enlarging mass in the right axilla extending into the chest wall. Magnetic resonance imaging and computed tomography revealed a large, multiloculated cystic lesion compressing adjacent neurovascular structures. Notably, the patient's history included resection of an oral lymphangiomatous mass during childhood, raising suspicion for a shared embryological origin. This case underscores the importance of considering lymphangiomas in the differential diagnosis of adult cystic masses and highlights the critical role of imaging in diagnosis and surgical planning.
