Definition / general
- Associated with HIV in U.S.

- Associated with HIV, lymphoma (non-Hodgkin and Hodgkin), myelodysplastic syndrome, eosinophilic cellulitis and nevoid basal cell carcinoma syndrome
Clinical features
- Three variants:
- Classic (Ofuji disease)
- Immunosuppression / HIV associated
- Infancy associated
- Clinically resembles acne
- No known cause
Microscopic (histologic) description
- Eosinophilic infiltration of hair follicle; follicular epithelium is spongiotic, adjacent dermis has lymphocytic and eosinophilic infiltrate
- Superficial dermal perivascular mononuclear and eosinophilic infiltrate
- Follicular mucinosis may rarely be seen
- Healing is associated with postinflammatory hyperpigmentation
