“A 33 year-old
male was diagnosed with Human immunodeficiency virus (HIV) infection in 2009, CD4 count of <200 cells/μL and HIV RNA 756000 cps/ml. Antiretroviral therapy (ART) was started. In 2010, a mass involving the rectum and bladder was diagnosed as a pelvic non-Hodgkin′s lymphoma (diffuse large B-cell lymphoma) and initially submitted to six cycles of chemotherapy—CHOP (Cyclophosphamide, doxorubicin, vincristine and prednisolone) and followed by radiotherapy RG7204 manufacturer (45 Gy), due to the persistence of the pelvic lesion. Six months later, a painful and progressively larger perianal lesion appeared complicating evacuation. A 15 cm × 10 cm exophytic mass of the perianal region
was observed (Figures 1 and 2). Laboratory tests showed normal hemoglobin level (15 g/dl), AZD1208 solubility dmso white blood cells count (4.68 × 109/L), platelets (232 × 109/L), CD4 count >200 cells/μL, and HIV RNA not detected. Endoscopic ultrasound (EUS) revealed an external anal sphincter defect. This HIV patient had a large, vegetative, cauliflower-like tumor in the perianal region, with local invasion revealed by EUS and histology confirming a condyloma acuminata (Figure 3). Anal Buschke Loewenstein Tumor (Giant Condyloma Acuminata) was diagnosed. This is a rare disease with a potentially fatal course, due to human papillomavirus (HPV) infection, most commonly HPV types 6 and 11 and occasionally types 16 and 18. It is characterized by its size, capability of local
infiltration, and high recurrence rate. There seems to be a trend towards younger age at presentation and male predominance. Perianal mass, pain, abscess, fistula and bleeding are the most common presenting symptoms. It most often affects the glans penis, but has also been reported in the scrotum, vulva, perianal region, and bladder. Local invasion and local recurrence are the major sources of morbidity in this disease. Despite the benign histological pattern in most cases, transformations into verrucous Tobramycin carcinoma and squamous-cell carcinoma have been described. Wide surgical excision, radiochemotherapy, topical and intralesional chemotherapy, carbon dioxide laser therapy, and photodynamic therapy have been used as treatment. Wide local excision remains the mainstay of therapy. The high recurrence rate after wide local excision has prompted the employment of therapy adjuncts. Both radiation and chemotherapy have been used as the most common preoperative regimen. This patient refused surgery and abandoned follow up. “
“Anti-TNF-α antibodies are effective in the treatment of inflammatory bowel diseases. These biologic drugs, however, may result in adverse effects that include opportunistic infections. Viral infections may also reactivate following immunosuppression.
