Cutaneous Bronchogenic Cyst in a 3-Year-Old Girl: A Case Report

Bronchogenic cysts commonly occur isolated in the bronchial tree, typically in the mediastinum. However, subcutaneous and cutaneous forms can rarely be found. Herein, we present a case of a 3-year-old girl with this lesion.

A 3-year-old girl presented to the clinic with an ulcerated plaque on her anterior chest wall. She mentioned a history of a skin-colored nodule on the same location that had been present since her birth, and was excised one year ahead with the diagnosis of epidermoid cyst. On examination, an ulcerative plaque was evident on the left midclavicular area with no tenderness, discharge, erythema, or regional lymphadenopathy. Incisional biopsy was performed. Histopathological study revealed non-dysplastic, squamous, pseudo-stratified, ciliated respiratory epithelium with diffuse inflammatory lymphomononuclear infiltration in the lower stroma, confirming the diagnosis of cutaneous bronchogenic cysts. The patient was referred for surgical resection of the lesion, but refused to continue the treatment.

Although lesions associated with skin appendages are more common in the diagnosis of subcutaneous masses, less frequent diagnoses should also be in mind for lesions with special localization or recurrent and unusual course, and histopathological examination of tissue specimens should be performed.</div>
