Unusual clinical tumor development in axilla

Area of Science:

• Oncology
• Pathology
• Radiology

Background:

• This case report details the clinical progression of a left axillary mass in a 36-year-old female.
• Initial presentation mimicked an enlarged lymph node with inflammatory signs.

Observation:

• Ultrasound revealed colliquation, and biopsy suggested inflammation, not malignancy.
• The mass rapidly enlarged from 2.5 cm to 10 cm within eight weeks.

Findings:

• Surgical excision enabled the definitive diagnosis of a small, mature-to-immature sarcoma.
• Histopathological examination could not precisely determine the sarcoma's tissue of origin (histogenesis).

Implications:

• This case highlights the importance of considering rare diagnoses even with initial benign findings.
• Aggressive tumor growth necessitates prompt surgical intervention for accurate diagnosis and treatment.
• Further histopathological analysis may be required for complex or rare sarcoma subtypes.
