32F w/ HIV, stared ART 9 mos ago (CD4 90, now 170), p/w 4 wks, slightly tender, hypertrophic vulvar lesion (representative pic π). Lives in US. Biopsy: no malignancy, culture (-).
Diagnosis? Differentials? @TxID_Edu @BradCutrellMD @DocWoc71 @Cortes_Penfield

Typical illness script for HSV esp in immunocompetent patients:
βοΈ painful ulcers, vesicles/group of vesicles that ulcerate
Among immunocompromised patients, HSV can also manifest atypically. πππ«π©ππ¬ π―ππ ππππ§π¬ is one of the atypical HSV manifestations.

βͺοΈ exophytic, verrucous, tumor-like presentation of HSV
βͺοΈ seen in immunocompromised patients, in particular people with HIV
Occurrence among people with HIV is independent of CD4 ncbi.nlm.nih.gov/pubmed/25660091 and no strong evidence w/ IRIS.

Thought to be a/w HIV-associated immune-dysregulation but exact pathogenesis is unclear:
βͺοΈ HIV-infected dendritic cells in the epidermis overproduce anti-apoptotic TNF & IL-6
βͺοΈ leads to keratinocyte proliferation and hyperkeratosis

Tends to be very difficult to treat. May not respond to courses of antiviral. Not unusual to receive cidofovir/foscarnet for c/f resistant HSV. Approaches that have been reported to be successful:
βͺοΈ Imiquimod
βͺοΈ Intralesional cidofovir
βͺοΈ Thalidomide
βͺοΈ Surgery + antiviral

Important to have an illness script for atypical HSV presentation.
Awesome DDx @TxID_Edu @Ornate_Brute @atrummedic! @CathalOBroin suspected it!
Expert consultation:
@DrStevenTChen Are there any other atypical HSV presentations clinicians need to know about?
