BACKGROUND Eccrine carcinoma is a quite rare malignant tumor that typically arises from a normal sweat gland and that features a rather high recurrence rate subsequent to simple excision. Given its rather poor response to adjuvant therapy, wide excision of the lesion with tumor-free margins may offer a reasonable chance for long-term control of this neoplasm. CASE PRESENTATION Herein, we repo...

Our previous study suggested that the alarm pheromones in rats could be divided into at least two functionally different categories: one evoking autonomic responses and the other evoking behavioral responses, and the present study was conducted to test this hypothesis. Four regions of the body surface, i.e. the whisker pad, neck, rump and perianal region, of an anesthetized male Wistar rat were...

Dear Editor, Giant condyloma acuminate (GCA) fi rst described by Buschke, also known as Buschke-Löwenstein tumour (BLT), is a slow growing, semi malignant neoplasm of the external genitalia and perianal region that has a recurrence tendency.1 Inspite of its histologically benign appearance, BLT clinically behaves in a malignant fashion, destroying adjacent tissues, and is reported as an entity ...

How common is it? The incidence of perianal infection caused by group A S pyogenes is not known, but since the first case descriptions in 1966 it has been reported in children from around the world. In a US general paediatric practice, perianal streptococcal disease was detected in one consultation per 300, and perineal disease (that is, perianal plus vulvovaginal disease) in one per 200. A 199...

Fournier's gangrene is a rapidly progressing necrotizing fasciitis, involving perineal, perianal, or genital regions, and it constitutes a true surgical emergency. Surgical excision of all necrotic tissue is required, and multiple debridements may be necessary to remove all nonviable tissue. After surgical intervention for debridement, reconstruction may be necessary. We present our experience ...

Mucinous adenocarcinoma associated with an anal fistula is a rare oncologic entity which may pose diagnostic and therapeutic challenges for Surgeons and Medical Oncologists. Few reported cases without definite therapeutic guidelines exist. It represents 2-3% of all gastrointestinal malignancies and arises from chronic anal fistulas, ischiorectal or perianal abscesses. We report a case of perian...

Tuberculosis cutis orificialis (TCO) is a rare manifestation of cutaneous tuberculosis that is caused by auto-inoculation of mycobacteria in patients with advanced internal tuberculosis. TCO occurs in oral, perianal, or genital mucosa and adjacent skin. The tongue is the most frequently affected site, but the perianal area can also be affected. A 39-year-old male presented with a 4-month histor...

Current evidence indicates that premalignant high-grade anal squamous lesions can progress to invasive anal carcinoma over time. Using cervical cancer prevention as a paradigm, anal cytology has thus been recommended as a primary screening tool for anal dysplasia in at-risk HIV-positive men.5,6 Men whose anal Papanicolaou (Pap) test yields abnormal results should undergo high-resolution anoscop...

OBJECTIVE To assess the safety and early postoperative results of ambulatory anorectal surgery using perianal anesthetics infiltration. MATERIAL AND METHOD This retrospective study included 222 elective ambulatory anorectal surgical patients under perianal anesthetics infiltration between March 2002 and September 2005. Perioperative pain, postoperative complications, and surgical outcomes wer...
