Eccrine porocarcinoma. Report of nine cases.

BACKGROUND: Eccrine porocarcinoma is a rare malignancy of the eccrine sweat gland and usually has a long-standing growth on a lower extremity. OBJECTIVE: The aim of this review was to analyze clinical and histopathological findings of eccrine porocarcinoma. METHODS: We report nine cases of eccrine porocarcinoma that we have seen during last 10 years. RESULTS: Eccrine porocarcinoma affects elderly patients in both sexes and is usually found on the lower extremities, but in our review it is similar on the head. The mean size was 1.9 cm in our cases. Elective primary treatment was excision and we did not perform elective lymph node dissection. We have not found evidence of metastases in any of our cases.

[Prominent ears. Correction using a modified Chongchet technique].

The authors describe their experience with the correction of prominent ears using a modified Chongchet technique. This method is based on the investigations of GIBSON and DAVIS (1958), who showed the tendency of cartilage to warp when one surface is cut. The prominent ear is folded back to produce the desired antihelix fold, which is outlined with methylene blue. An elliptical piece of retroauricular skin is excised. An incision is made through the whole thickness of the cartilage, following the posterior marked linea of the new antihelical fold, from the superior crus to the tail of antihelix. The anterior surface of the cartilage is dissected from the skin. A series of parallel incisions are made through the taut outer layer of the future fold. The tension on that side is released, and therefore it will bend towards the opposite side. The antihelical fold is corrected. This method was used in 192 patients with prominent ears. The results were satisfactory, with a normal-looking fold of antihelix. No recurrence of the deformity was seen.

[Endoscopic injection of autologous adipose tissue in the treatment of female incontinence].

We describe a new procedure utilizing autologous fat instead of teflon injection in the treatment of female urinary incontinence that is equally useful in correcting postadenomectomy incontinence in the male and vesicoureteral reflux. We have used this new procedure over the past 4 months in 10 patients with urinary stress incontinence and no concomitant cystocele. The procedure is performed under spinal anesthesia. Small cylinders of subcutaneous abdominal fatty tissue are obtained by microliposuction. The fat graft in the form of four 10 ml. wheals is then injected in the vesical neck. We emphasize that this technique is simple and there are no complications. The low cost of this technique requiring a 24 h stay at the hospital affords additional advantages. Likewise, the procedure can be repeated or subsequent surgical procedures can be performed without difficulty in the event correction is unachieved.

[Reconstructive techniques in cutaneous defects of the nasal tip].

Many techniques are used for repairing nasal tip defects. Our own guidelines are reviewed: Small defects often can be closed directly. Lesions of the nasal tip over 0.5 cm in diameter usually require a skin graft or flap. Postauricular, preauricular, and nasolabial full-thickness skin grafts may produce noticeable color or contour differences. The type of local skin flap used depends on defect size: Local rotation-transposition flaps or the nasalis myocutaneous sliding flap described by Rybka are used for defects 2 cm or less in diameter. Rieger and de Marchac frontonasal flaps are used for defects 2-3.5 cm in diameter. Forehead flaps are used for defects of 3.5 cm or more. We prefer Rybka's flap for nasal tip defects less of 2 cm because it has cosmetic advantages: incisions do not deform natural cutaneous crease lines and chronic edema and "dog ears" secondary to rotation-transposition pedicle flaps are avoided. For more extensive defects, we prefer frontonasal or forehead flaps.
