Superficial and deep-seated tuberculous lesions: fine-needle aspiration cytology diagnosis of 574 cases.

Over a period of 2 yr (1987-1988), FNA smears in 574 cases were found to have cytologic features suggestive of or consistent with tuberculous lesions. The age of the patients ranged from 6 mo to 75 ye, with a median of 24 yr. The male to female ratio was 273:301. Sites of FNA were superficial lymph nodes (SLN) in 440 (76.7 percent) cases, superficial extranodal sites (SENS) in 50 (8.7 percent), both SLN and SENS in 7 (1.2%), the thoracic cavity in 16 (2.8%), and the abdominal cavity in 61 (10.6%). Cytologic features were described under 3 major cytologic patterns, i.e., type I: epithelioid granuloma without necrosis, type II: epithelioid granuloma with necrosis, type III: necrosis without epithelioid granuloma. Type I, II, and III reactions were observed in 181 (31.5%), 183 (31.9%), and 210 (36.6%) cases, respectively. The overall AFB positivity was 30.8%. The AFB positivities for type I, II, and III cytologic reactions were 5.4%, 32.0%, and 48.5%, respectively. The AFB positivity was low (less than 30.0%) in swellings of the body surface (23.8%) and abdominal organs (18.9%). High positivity (greater than 60.0%) was observed in lesions of the thorax (63.6%) and thyroid (62.5%).

Inflammatory lesions of the breast: diagnosis by fine needle aspiration.

Amongst 1061 breast lesions diagnosed by fine needle aspiration (FNA) over a period of 6 years (1985-1990), 128 were reported to be showing changes consistent with an inflammatory lesion. On review, the cytodiagnosis was found to be inaccurate in 31 cases. The cytological features of the 97 cases that were correctly reported are described in this report. The cytological diagnoses issued in these 97 cases were acute mastitis or breast abscess (57 cases) and tuberculous mastitis (30 cases). Non-specific chronic mastitis and miscellaneous conditions accounted for four and six cases respectively. Acid fast bacilli (AFB) were demonstrated in 28.0% of tuberculous mastitis cases and 10.0% of those diagnosed as acute mastitis or breast abscess. FNA cytology was found to be useful for the diagnosis of inflammatory lesions of breast and their classification, as only five out of 57 cases of acute mastitis/breast abscess and one out of 30 tuberculous mastitis cases were suspected on clinical grounds.

A new technique for chronic venous ulcers of the lower limb: modified Felder-Rob procedure.

Subfascial ligation of perforating veins is a commonly performed operative procedure for chronic venous ulcers of the leg. The most widely adopted incision currently used is the posterior midline approach described by Felder. This, however, is associated with significant morbidity due to necrosis of skin overlying the tendo Achillis with consequent exposure-induced necrosis and contracture of the tendon. A new incision based on anatomical studies is described. The procedure was adopted in 45 limbs with chronic venous ulcers. The incision is associated with very minimal morbidity and has given excellent results in the form of a major necrosis rate of only 4.4% (none of which involved the skin over the tendo Achillis or the tendon itself) and an ulcer recurrence rate of 4.4% during the period of follow-up of 2-8 years.

Retroperitoneal colopexy for adult rectal procidentia. A new procedure.

Nonresective fixation procedures are superior to resections in the management of rectal procidentia. A new operative procedure of retroperitoneal fixation of the redundant rectum and sigmoid after mobilization of the rectum up to the pelvic floor is described. The procedure was performed in 32 patients. In a follow-up ranging up to 11 years, only one recurrence of mucosal prolapse was seen. Rectal, bladder, and sexual functions were normal. There was a low wound infection rate and no mortality. The procedure appears superior to conventional operations for rectal procidentia and, at the same time, avoids usage of prosthetic materials for fixation with their known risk of complications.

Dartos-based scrotal myocutaneous flaps: their place in regional reconstructions.

Injection studies were done in cadavers to demonstrate the blood supply of scrotal flaps and lay the foundation of the basis of their use in regional reconstruction. Eighty-seven scrotal flaps, antero-lateral, posterior, extended posterior and bipedicled (including de-epidermized flaps) were used as peninsular or island flaps in 60 patients and 64 situations. The flaps were used for lengthening of phallus stumps, neophalloplasty, providing groin cover, urethral repair, construction of simulated testis, hernioplasty and for providing cover in a precise manner after scrotectomy in filarial scrotum and other conditions.

Genital amebiasis.

Five cases of amebiasis of the genital tract involving the cervix, vulva and penis are described. All presented as an ulcerating mass and were clinically suspected to have a tumor. In two cases the amebiasis co-existed with a carcinoma, an association which is extremely rare. The spouse of a patient with penile amebiasis was found to have amebiasis of the cervix suggesting a sexually transmitted mode of infection. The need for histopathological confirmation of all suspected genital malignancies is emphasised due to the striking resemblance of genital amebiasis to a carcinoma. The co-existence of amebiasis with carcinoma is of interest and suggests a possible etiological relationship.

Refashioning of phallus stumps and phalloplasty in the treatment of carcinoma of the penis.

The surgical management of 41 patients with carcinoma of the penis is presented. Conservative surgery in the form of a circumcision or a glansplasty was done in eight patients with one recurrence. Circumcision as an adequate procedure is advocated for lesions near the apex of the preputial sac permitting a 2 cm clearance; glansplasty after local excision requires further evaluation. The details of technique of lengthening and refashioning of the residual phallic stump after partial amputation in a further 20 patients is described using a technique which leaves a satisfactory penile stump in patients who would normally be candidates for a total amputation. In a third group of patients requiring a total amputation of penis, reconstruction was done in two stages using scrotal flaps in four with satisfactory results. The reconstructed phallus was adequate as a urinary conduit but was unsuitable for sexual function. A one stage procedure involving covering of the urethra with scrotal flaps appears an attractive alternative to the staged procedure. Conventional multistage reconstructions are not recommended.

The total gluteus maximus rotation and other gluteus maximus musculocutaneous flaps in the treatment of pressure ulcers.

The use of musculocutaneous flaps in the treatment of pressure ulcers has been widely accepted. This study presents the results of the use of various types of gluteus maximus musculocutaneous flaps such as island flaps, advancement flaps and new total gluteus maximus rotation flaps with or without an inferior gluteal fasciocutaneous extension, in the treatment of pressure ulcers.

Gluteus maximus myocutaneous flap cover for sacral radiation ulcers.

Myocutaneous flap cover of postirradiation ulcers has recently been recognized as a useful and effective method of treating these non-healing ulcers. This study presents the results of three cases of postirradiation sacral ulcers treated by gluteus maximus myocutaneous flaps. In one case a conventional island flap was used, whereas in the other two cases a new technique of a total rotation gluteus maximus myocutaneous flap is described.
