Painful Axillary Mass in Adolescent Male

Gender: Male
Age: 16

Case at a Glance

A 16-year-old male presents with a painful mass in the left axilla of several days duration, causing significant discomfort with arm movement and daily activities.

Patient's Story

The patient reports the sudden appearance of a small, painful bump in his left armpit approximately 3-4 days ago. He describes severe pain that significantly limits his ability to lift his arm or perform basic activities such as removing his shirt. This is the first occurrence of such symptoms for the patient. He expresses concern about potential sexual causes and questions whether masturbation could be related to his condition. The patient is seeking guidance on whether immediate medical attention is necessary or if conservative management is appropriate.

Initial Assessment

Physical examination would likely reveal a tender, palpable mass in the left axillary region. The patient demonstrates limited range of motion in the left upper extremity secondary to pain. No systemic symptoms reported at this time.

The Diagnostic Journey

Differential diagnosis includes sebaceous cyst, hidradenitis suppurativa, lymphadenopathy (infectious or inflammatory), abscess formation, or folliculitis. Given the acute onset and significant pain, infectious or inflammatory causes are most likely. The patient's concerns regarding sexual activity and masturbation as causative factors were addressed, as these are not related to axillary masses.

Final Diagnosis

Based on clinical presentation, the most probable diagnosis is an infected sebaceous cyst or early abscess formation in the axillary region.

Treatment Plan

Immediate medical evaluation is recommended given the severity of pain and functional limitation. Treatment may include antibiotic therapy if bacterial infection is suspected, warm compresses for symptomatic relief, and possible incision and drainage if abscess formation is confirmed. Patient education regarding proper hygiene and reassurance that the condition is unrelated to sexual activity.

Outcome and Follow-up

Patient advised to seek prompt medical attention rather than waiting, as early intervention can prevent complications and provide faster symptom resolution. Follow-up care would depend on the specific treatment provided and clinical response.
