Sweet's syndrome and eosinophilic folliculitis are aseptic inflammatory dermatitis mainly because of infiltrated neutrophils and eosinophils on skin, respectively. These diseases rarely overlap or coexist in the same patient, especially co-occur in HIV infected patient. Here, we report a rare case of an AIDS patient who developed eosinophilic folliculitis and Sweet's syndrome within 1 month of initial antiretroviral therapy, presumably due to immune reconstitution inflammatory syndrome. The CD4 + T cell counts increased dramatically from 70 to 249 cells/µL within a period of 1 month. Interestingly, the patient was rapidly and strikingly responsive to thalidomide, which has anti-inflammatory, immune regulation, inhibition of neutrophil chemotaxis etc. Moreover, we focused our attention on discussing the clinical, pathological, and possible pathogenic aspects of the rare overlap of HIV complicated with neutrophilic and eosinophilic dermatosis.

Background: The clinical and laboratory characteristics of AIDS-associated Talaromyces marneffei infection, a rare but a fatal mycosis disease of the central nervous system, remain unclear. Case presentation: Herein, we conducted a retrospective study of ten AIDS patients with cerebrospinal fluid culture-confirmed central nervous system infection caused by Talaromyces marneffei. All 10 patients were promptly treated with antifungal treatment for a prolonged duration and early antiviral therapy (ART). Among them, seven patients were farmers. Nine patients were discharged after full recovery, while one patient died during hospitalization, resulting in a mortality rate of 10%. All patients initially presented symptoms and signs of an increase in intracranial pressure, mainly manifesting as headache, dizziness, vomiting, fever, decreased muscle strength, diplopia or even altered consciousness with seizures in severe patients. Nine patients (90%) showed lateral ventricle dilatation or intracranial infectious lesions on brain CT. Cerebrospinal fluid findings included elevated intracranial pressure, increased leukocyte count, low glucose, low chloride and high cerebrospinal fluid protein. The median CD4 + T count of patients was 104 cells/μL (IQR, 36-224 cells/μL) at the onset of the disease. The CD4 + T cell counts of three patients who eventually died were significantly lower (W = 6.00, p = 0.020) than those of the patients who survived. Conclusions: The common clinical symptoms of T. marneffei central nervous system infection are associated with high intracranial pressure and intracranial infectious lesions. Earlier recognition and diagnosis and a prolonged course of amphotericin B treatment followed by itraconazole combined with early ART might reduce the mortality rate.

Cutaneous disorders remain a major problem in HIV‐infected patients, even under antiretroviral therapy (ART). Patients at any stage of HIV/AIDS may suffer from skin lesions. Acnes and psoriasis are both common chronic and inflammatory skin diseases, and the treatment becomes more challenging and complex when combined with HIV infection. Whether the incidence and severity of acne and psoriasis are related to HIV infection is still controversial. Here, we report a rare case of an AIDS patient who developed severe acne along with psoriasis. The patient had initially received multiple systemic and topical antipsoriatic and anti‐acne treatments which failed. Ultimately, he achieved dramatic clinical improvement after initiation of ART for main treatment. An 8‐year follow up demonstrated that the patient has been free of symptoms of both psoriasis and acne till now.
