Cutaneous heterotopic bronchogenic tissue in the scapular area

Area of Science:

• Dermatology
• Pathology
• Surgical Pathology

Background:

• Cutaneous bronchogenic anomalies are uncommon congenital malformations.
• They typically manifest as subcutaneous cysts or sinus tracts.
• Diagnosis often relies on histopathological examination.

Observation:

• A 15-year-old male presented with a crusted, papillomatous plaque on his right scapula.
• The lesion lacked typical cyst or sinus tract formation.
• Histology revealed pseudostratified ciliated columnar epithelium with papillary features.

Findings:

• The plaque contained mucinous material within papillary invaginations.
• Smooth muscle bundles were identified in the lesion's stroma.
• This presentation differs from classic cutaneous bronchogenic anomalies.

Implications:

• This case expands the spectrum of cutaneous bronchogenic anomaly presentations.
• It underscores the importance of thorough histopathological evaluation for rare cutaneous lesions.
• Further research may clarify the pathogenesis of these diverse presentations.
