An Algorithmic Anatomical Subunit Approach to Pelvic Wound Reconstruction.

BACKGROUND: Prior radiation therapy, pelvic dead space, and a dependent location contribute to perineal dehiscence rates as high as 66 percent after primary closure of pelvic wounds. Various regional flaps have been described to reconstruct pelvic defects, but an algorithmic pairing of individual flaps to specific anatomical regions has not been described. METHODS: A retrospective review of a prospectively maintained database was performed to identify consecutive pelvic reconstructions from 2010 to 2013 with at least 6 months' follow-up. Pelvic defects and resulting flaps were described by anatomical subunits involved: anterolateral thigh flap for mons, gracilis flap for labia majora and introitus, vertical rectus abdominis myocutaneous flap for vagina and/or perineal raphe, and gluteus musculocutaneous flap for isolated perianal defects. RESULTS: Twenty-seven women and three men underwent consecutive pelvic reconstruction with a mean age of 60 years (range, 26 to 83 years) and a mean body mass index of 28 kg/m(2) (range, 17 to 40 kg/m(2)). Twenty-one patients (70 percent) had prior radiation therapy. In total, 45 flaps were performed according to the subunit principle. Three patients had a minor dehiscence (<5 cm), one patient had a major dehiscence, and one required reoperation for abscess. There were two partial flap losses necessitating débridement and readvancement of the flap. Twenty-five percent of female patients were sexually active after vaginal reconstruction. CONCLUSIONS: The pelvic subunit principle provides an effective algorithm for choosing the ideal pedicled flap for each region involved in acquired pelvic defects. This algorithm is based on individual attributes that make each flap most appropriate for each subunit. Complications were minimal and patient satisfaction with appearance and function was excellent.

Rhinosporidiosis affecting multiple parts of the body.

Rhinosporidiosis is a rare chronic granulomatous condition caused by a fungus (Rhinosporidium seeberi). It has been seen mainly in southern India, Sri Lanka and Pakistan. This is the first published report of a patient with multiple rhinosporidiosis. He had lesions in the nares, in multiple areas of the skin, in the external urethral meatus, glans of penis and the perineum.

[Investigating Demodex folliculorum in patients with urological cancer]. / Ürolojik Kanserli Hastalarda Demodex folliculorum Arastirilmasi

OBJECTIVE: In this study, it was aimed to determine frequency of Demodex folliculorum infestation in patients with urological cancers. METHODS: This study evaluated 49 patients with urological cancers; 31 sex-matched healthy individuals as a control group were included in the study between March 2011 and April 2012 at the Hospital of Mustafa Kemal University, School of Medicine, Urology Clinic. The demographic characteristics of the patients were recorded. Samples from the perineal region of the subjects were taken by standard method of superficial skin biopsy and evaluated by microscopy. Presence of five or more Demodex sp. in a cm < sup > 2 < /sup > was considered as positive. RESULTS: Mean age was found to be 60.2±18.6 years. D. folliculorum was found to be positive in 11 (22.4%) of the patients with cancer and in 1 (3.2%) of the subjects in the control group. It was found that D. folliculorum frequency was significantly higher in the cancer group compared to the control group. No significant difference was found among the cancer groups in terms of D. folliculorum detection. In the cancer group, mean age was significantly higher in D. folliculorum positive patients than negative ones. CONCLUSION: It should be kept in mind that D. folliculorum incidence may increase in immunosuppressive states, such as cancer.

The prevalence of Demodex folliculorum on the scrotum and male perineal skin.

Demodex folliculorum (D. folliculorum) is a human ectoparasite that resides in the pilosebasceous skin unit. Common sites of predilection are the skin of cheeks, forehead, nose, nasolabial fold and eyelids. Genital D. folliculorum inoculation case reports are extremely rare and depend on investigation of skin lesions. There is no study of genital skin without lesions, and, as far as we know, there is no literature on D. folliculorum prevalence in male genital skin. We examined D. folliculorum prevalence on the healthy scrotum and male perineum. One hundred males were examined for D. folliculorum on facial and genital skin. Samples were taken from cheek, forehead, scrotum and perineum by standard skin surface biopsy (SSSB) or hair epilation. The mean age was 53.5+/-13.0 (24-70) years. Eight percent of males had D. folliculorum on their facial skin. Mean Demodex density (Dd) of men with D. folliculorum positivity was 5.1+/- 2.9/ cm (2)(2-9/cm(2)). Diagnostic results of both sampling methods were similar. No D. folliculorum was demonstrated on genital skin.

Perineal nodule due to enterobiasis: an aspiration cytologic diagnosis.

Subcutaneous swelling due to Enterobious vermicularis infection is rare. Their presence in perineal subcutaneous tissue is unusual and a clinical curiosity. A case of subcutaneous nodule in the perineum due to E. vermicularis infection diagnosed on fine-needle aspiration is described. Tissue reaction was granulomatous with neutrophils and eosinophils. Lack of familiarity with the morphology of parasites or its eggs, degeneration, and inadequate sampling may make the diagnosis difficult. This case report provides the morphologic clues to cytopathologists toward rendering a diagnosis and alerts them to the possibility of parasitic infection in unusual locations.

Amibiasis cutánea: presentación de dos casos / Cotaneous amebiasis: two cases report

La localización en la piel de la amiba no es tan frecuente como sus localizaciones intraintestinal o el abceso hepático amibiano. Es una enfermedad grave si el diagnóstico y el tratamiento no son realizados en forma oportuna. Se presentan dos casos de amibiasis cutánea con buena respuesta al tratamiento.
