RESUMEN

We report the first case of detection of sentinel node in a 54 year-old woman presenting an adenocarcinoma of Bartholin's gland. Primary carcinoma of Bartholin's gland is rare and represents 2-7% of vulvar malignant lesions; this could explain the lack of consensus about treatment. The best attitude could be vulvectomy and inguinal lymphadenectomy. Pelvic lymphadenectomy is not required when no pelvic sentinel node is observed or when no metastatic inguinal node can be detected.

RESUMEN

In the present study we used computer-assisted microscopy to analyze the morphology of Feulgen-stained cell nuclei in cell populations obtained at the same time as routinely performed cervical smears and in the same way. We investigated in a series of 110 cases whether the quantitative morphonuclear description of cytological cervical samples is able to aid pathologists to distinguish between benign and more suspect premalignant lesions. For this task nuclear DNA content, nuclear morphometry (size and anisonucleosis level) and chromatin pattern-related parameters were compiled for each specimen enrolled in the database. A set of 32 normal and 17 high-grade squamous intraepithelial lesion (HSIL) specimens (with diagnostic confirmations) were selected as references and used to establish a discriminant model on the basis of cytometry-generated variables. This model was then used to score the remaining 61 cases in our series (including cases exhibiting benign cellular changes, squamous cells of undetermined significance, low-grade SIL and cancers). The results show that a model discriminating efficiently between normal and HSIL groups can be obtained by combining 5 quantitative features (1 DNA ploidy-related, 2 morphometrical and 2 chromatin texture features). A 97% specificity and an 88% sensitivity characterized the boundary so established. When applied to new cases, the model was in fact able to correct diagnoses for cases which had been down- or up-graded on the basis of the Bethesda system, and provided scores in accordance with histological control.

RESUMEN

The leiomyosarcoma are rare tumors, accounting for only 0.1% to 3% of all gastrointestinal malignancies. 150 new cases are diagnosed annually in the United States. The spectacular character of leiomyosarcoma consists in its measurements, its size reaching 35 x 25 x 17 cm, its weight 5.5 kg, and in the asymptomatic character of the tumor. The final diagnosis, although suspect with preoperative diagnostic procedure, is obtained after histologic examination. Complete surgical excision is the best treatment, the role of radiation therapy and chemotherapy are not yet established.

RESUMEN

Despite contradictory information about the course and distribution of the nerves supplying the breast, surgical techniques using an inferior pedicle have been recommended over those using a superior pedicle for preserving the nipple-areolar sensation after surgery. This anatomical study was designed to quantify the nerve branches preserved in inferior and superior pedicles after reduction mammaplasty performed on cadavers. Reduction mammaplasty was done on four fresh cadavers (within 48h of death) using a superior pedicle on the right and an inferior pedicle on the left in a standard way. The pedicle was cut at its base and then fixed in formalin. The base was divided in biopsy specimens and embedded in paraffin. The nerves were quantified and located in each pedicle with haematoxylin-eosin stain and light-microscopic evaluation. Histological evaluation of the pedicles showed the presence of a variable number of nerves (between one and seven) within two superior pedicles and three inferior pedicles. The nerves were located in fibrous tissue and accompanied by vessels in most cases. The nerves were always found superficially and were most likely to be located in the central part of the pedicle. Our results showed that including the nerves within the pedicle is technically uncertain regardless of the mammaplasty technique used. The final recovery of sensation in the breast after mammaplasty seems to result from the regeneration of severed cutaneous nerve branches or the remaining cutaneous innervation rather than the preserved adjacent cutaneous branches.

RESUMEN

Paget's disease is uncommon in patients younger than 50 years of age. Multifocal giant cell tumors arising in bone affected by Paget's disease have been described previously in 37 cases. A case of a 38-year-old man with polyostotic Paget's disease and multifocal giant cell tumors responsive to steroid therapy is presented.

RESUMEN

The distinction between benign and malignant smooth muscle tumours relying on histological features such as the mitotic index and pleomorphism remains a generally acknowledged difficulty in modern pathology. A cell image processor was therefore used to quantitatively assess the desmin and vimentin immunostain in 39 smooth muscle tumours which included 26 benign (leiomyomas) and 13 malignant (leiomyosarcomas) cases. The 13 leiomyosarcomas were primary (non-recurrent and non-metastatic). Ploidy level and cell density were also assessed on each of these 39 tumours by means of the computer-assisted microscopic analysis of 5-microns thick Feulgen-stained histological sections. The results show that while neither the ploidy level determination nor the quantitative assessment of the vimentin immunostain made it possible to distinguish between leiomyomas and leiomyosarcomas, cell density determination and the quantitative assessment of the desmin immunostain enabled such a distinction to be made. Indeed, the leiomyomas exhibited a much higher level of desmin positivity than the leiomyosarcomas, as did diploid tumours as compared to the aneuploid (benign or malignant) ones. Furthermore, the leiomyoma group exhibited a significantly lower mean cell density value than the leiomyosarcoma group. The present study further confirms the lack of relationship between ploidy level and cytological malignancy in smooth muscle tumours.

RESUMEN

Among skin cancers, basal cell carcinoma (BCC) is considered as a relatively indolent disease. Sometimes, these carcinomas have an unusual clinical behaviour, with extreme aggressiveness. Based on reports of eight cases of aggressive BCC of the head and neck areas, and after a review of the literature, we define three criteria of aggressiveness: (1) initial diameter greater than 1 cm, (2) more than two recurrences despite all tentative conclusions of adequate treatment, or (3) extension into any extracutaneous structure.

RESUMEN

In order to properly advise cardiac patients in the regulation of their sexual activity, more basic physiologic information is needed concerning the cardiovascular effects of sexual intercourse. This study examined the effects of the male's position during sexual intercourse on heart rate and blood pressure responses. Eight men, 24 to 40 years of age, were studied in the privacy of the bedroom during sexual activity with their wives. The ECG was monitored continuously by portable tape recorder and the arm blood pressure (BP) was measured intermittently with an automatically inflated cuff and ultrasonic detector device controlled by the subject. A total of 35 episodes of sexual intercourse were monitored; 16 were with the male-on-top (MOT) and 19 were in the male-on-bottom (MOB) position. The mean maximal heart rate (HR) for MOT at orgasm was 114 compared to 117 in the MOB position, representing 61 per cent of predicted maximal HR for men in the 20 to 29 age group. Mean BP at orgasm in the MOT was 163/81 and 161/77 in the MOB position. The differences in mean HR, BP, and pressure rate product (PRP) were not statistically significant with regard to position at rest intromission, orgasm, or during the recovery period. This study indicates no difference in the heart rate and BP responses of the male during sexual intercourse in two different positions. There is, therefore, no physiologic basis for advising cardiac patients to utilize the MOB position during sexual intercourse.
