Case for diagnosis. Chondroid syringoma.

Area of Science:

• Dermatology
• Pathology
• Oncology

Background:

• Chondroid syringoma, or mixed cutaneous tumor, is a rare benign neoplasm originating from sweat gland elements.
• It features both epithelial and mesenchymal components within diverse stromal types (cartilaginous, collagenous, myxoid, osseous).
• Typically affects middle-aged men, presenting as asymptomatic, slow-growing dermal or subcutaneous nodules, most commonly on the head and neck.

Observation:

• Malignant variants are infrequently reported, predominantly in women and often located on the extremities.
• This report details a rare case of a chondroid syringoma occurring on the toe of a female patient.
• The lesion presented as a nodule, consistent with typical presentations though rare in this location.

Findings:

• The patient, a woman, presented with a chondroid syringoma on her toe.
• Surgical excision was performed as the treatment modality.
• The outcome following surgical intervention was excellent, with no recurrence noted.

Implications:

• This case expands the understanding of chondroid syringoma presentation, particularly its occurrence on extremities in women.
• It underscores the importance of considering this rare tumor in the differential diagnosis of extremity lesions.
• Successful surgical management indicates a favorable prognosis for extremity chondroid syringoma, even in atypical patient demographics.
