Deep Cystic Lymphangioma on the Chest Wall in an Adult / 대한피부과학회지

ABSTRACT

Cystic lymphangioma is a true, benign, congenital multicystic tumor arising from sequestrations of embryonic lymphatic tissue. Most often it occurs at birth or during the early years of life, is found most commonly in the neck, and its distribution coincides with that of the primitive lymph sacs. A 23-year-woman presented with a soft palpable mass on her chest wall. Physical and ultrasound examination revealed a well-circumscribed, mobile, nontender, soft subcutaneous mass on the right posterior chest wall beneath the latissimus dorsi muscle. A skin biopsy of the mass showed endothelium-lined lymphatic vessels and a loose, lace-like fibrous tissue stroma. The specimen was stained with D2-40 showing positive staining of lymphatics. These histopathological findings confirmed the diagnosis of a cystic lymphangioma. We report a rare case of a cystic lymphangioma on the chest wall in a 23-year-old woman.
