Summary
Alopecia areata (AA) may present with a distinct rectangular pattern in the occipital area. This specific presentation was observed in three patients with underlying conditions including lymphoma and vascular malformations.
Area of Science:
- Dermatology
- Oncology
- Neurology
Background:
- Alopecia areata (AA) is an autoimmune condition often linked with other autoimmune disorders.
- AA can also manifest as a paraneoplastic symptom in patients with malignancies.
Observation:
- This report details three distinct cases presenting with alopecia areata.
- The patients exhibited a characteristic rectangular pattern of hair loss specifically on the occiput.
Findings:
- Case 1: Patient with diffuse large B-cell lymphoma.
- Case 2: Patient with alveolar soft part sarcoma.
- Case 3: Patient with a cavernous sinus arteriovenous fistula treated with embolization.
Implications:
- The rectangular occipital alopecia pattern may serve as a clinical indicator for underlying systemic diseases.
- Further research is warranted to explore the association between this specific AA presentation and systemic conditions like cancer and vascular abnormalities.
