Ganglion cell like cells, diagnostic dilemma.

Area of Science:

• Dermatopathology
• Oncology
• Surgical Pathology

Background:

• Ganglioneuromas are rare, benign tumors typically found along sympathetic ganglia or in the adrenal medulla.
• Primary cutaneous ganglioneuromas are exceptionally rare.
• Cutaneous swellings can present diagnostic challenges.

Purpose of the Study:

• To report a rare case of a cutaneous swelling initially diagnosed as ganglioneuroma.
• To investigate the histological and immunohistochemical features of the lesion.
• To emphasize the importance of advanced diagnostic techniques for cutaneous lesions.

Main Methods:

• Histopathological examination using Hematoxylin and Eosin (H and E) staining.
• Immunohistochemical analysis to determine cellular origin.
• Gross examination of the excised dermal specimen.

Main Results:

• The excised nodule showed spindle cells with ganglion cell-like features on H and E staining, initially suggesting ganglioneuroma.
• Immunohistochemistry revealed a fibroblastic origin.
• The final diagnosis was fibromatosis with ganglion cell-like fibroblasts.

Conclusions:

• The histological features of ganglioneuromas can be mimicked by other cutaneous lesions.
• Diagnosis solely based on H and E staining can be misleading for cutaneous ganglioneuromas.
• Immunohistochemistry is crucial for accurate diagnosis of such rare skin tumors.
