Primary peritoneal mesodermal adenosarcoma: report of a case and review of the literature.

BACKGROUND: Mesodermal (müllerian) adenosarcoma arising from the peritoneum is rare and is thought to arise from pluripotent mesothelial and mesenchymal cells of the pelvic cavity or from endometriotic deposits. CASE: A case of primary peritoneal mesodermal adenosarcoma arising from the omentum is described. A 50-year-old woman presented with sudden abdominal distension. Initial laparotomy revealed a 13-kg mass arising from the omentum, which was determined from frozen and paraffin sections to be serous cystadenofibroma. The tumor recurred within 10 months and weighed 18 kg at a second laparotomy. Histopathology and review of the original tumor established the correct diagnosis of mesodermal adenosarcoma. The patient died from disseminated disease 6 months later. CONCLUSION: Adenosarcomas are difficult to differentiate from adenofibromas or endometriosis histologically because of the presence of large areas of low cellularity and infrequent mitotic figures. In such cases, stromal nuclear atypia and periglandular stromal cuffing are features that are diagnostic of adenosarcoma.

Vulval squamous cell carcinoma arising in chronic hidradenitis suppurativa.

Hidradenitis suppurativa is a chronic inflammatory disease of the sweat glands and hair follicles which is rarely associated with squamous cell carcinoma (SCC). A case of vulval SCC complicating hidradenitis suppurativa is presented. In addition to being the first case to report the association of vulval SCC and hidradenitis suppurativa in the English language literature, it also illustrates the difficulty inherent in distinguishing between invasive SCC and pseudoepitheliomatous hyperplasia on histological examination. The success of wide local excision of the vulval lesion and primary closure without recourse to skin grafts, rotational flaps, or healing by secondary intention is demonstrated.

[The applicability of phleboscintigraphy in diagnosis and treatment result evaluation of patients with disorders of leg venous circulation].

The aim of the paper was the applicability of phleboscintigraphy in the diagnosis and monitoring of the treatment in patients with various disorders of venous circulation in lower extremities. The study comprised eighty-eight patients with the suspicion of deep veins impatience. The examination was performed using DTPA 99mTc by means of a gamma camera connected with a computer. The radioisotope was injected into the foot dorsal veins. The dose was 185 MBq. Its activity was monitoring continuously for 1 min. The estimation of the results was performed by scintigraphy imaging and curves of activity changes of chosen regions over deep veins. Phleboscintigraphy was found out to be of a great value in the diagnostics and assessment of treatment results in thrombotic-embolic disease, extra-thrombotic syndromes and in qualification of patients with lower legs varices for surgical procedures. Because of easy performance, possibility of repeating, small invasiveness and rather low cost, the method can be recommended as an introductory examination in patients with above mentioned diseases.

[Analysis of iatrogenic injuries in 1988-1996].

The analysis of 77 iatrogenic injuries observed in the authors department in the group of 75 patients was conducted. Immediate repair was performed in 71 cases. Serious complications were noticed in 11 cases. 7 patients died in the consequence of the injury.

Re-evaluating the need for hospitalization following synovectomy using Yttrium-90 silicate.

In 51 patients treated with Yttrium-90 (Y-90) synovectomy for rheumatoid (inflammatory) arthritis (IA) and OA of the knee we found that decreased retained knee activity (RKA) and increased extra-articular activity in lymph nodes and liver are more likely to be found in IA than OA and following bilateral knee injections. Joint inflammation, as assessed by radionuclide blood pool scan but not by SF white cell count, correlates with decreased RKA and increased activity in lymph nodes. Intra-articular steroid had no significant effect on retention or extra-articular uptake. Strict hospital immobilization improves RKA of Y-90 in IA but not in OA. Y-90 synovectomy in OA shows good RKA and low extra-articular uptake. We recommend strict immobilization following Y-90 synovectomy, particularly in IA patients and/or those with high joint blood flow.

In-situ hybridization using biotinylated DNA probes to human papillomavirus in adenocarcinoma-in-situ and endocervical glandular dysplasia of the uterine cervix.

In-situ hybridization using biotinylated probes to human papillomavirus (HPV) DNA was performed on formalin fixed paraffin embedded tissue in 30 patients with histologically confirmed adenocarcinoma-in-situ (AIS). Thirteen of the 30 cases contained areas of endocervical glandular dysplasia (EGD) admixed with AIS. Twenty one patients showed positive staining of the AIS nuclei for HPV DNA. Ten cases (33%) were positive for HPV 16 DNA and 11 cases (37%) were positive for HPV 18 DNA. No case showed synchronous expression of HPV 16 and 18 DNA. All cases of AIS were negative for HPV 6b and 11 DNA. Four cases of EGD were positive for HPV 18 DNA and 2 cases were positive for HPV 16 DNA. Four of 6 cases of intestinal dysplasia/AIS were positive for HPV 18 DNA. Associated squamous abnormalities (HPV +/- CIN +/- SCC) were noted in 15 cases. Of these, 7 showed positive staining for HPV DNA in the squamous lesion. Moreover, 5 of these were positive in both the AIS and squamous lesion. In-situ hybridization using biotinylated DNA probes is a sensitive and safe technique readily adaptable to routine histopathology.

Hookworm folliculitis.

A case of persistent folliculitis in a 21-year-old man was demonstrated to be due to Ancylostoma caninum larvae. Treatment with oral thiabendazole was curative. Cutaneous larva migrans may be due to A caninum, but this presentation appears to be unique. The literature concerning etiology and pathogenesis of larva migrans is discussed with reference to this case.

The turtle's revenge: a case of soft tissue Mycobacterium chelonae infection.

A case of cutaneous Mycobacterium chelonae infection with sporotrichoid spread and extensive antibiotic resistance is presented. Control of this problem was only achieved after extensive debridement and grafting of the involved limb. The importance of surgery in management is discussed and the literature is reviewed.

Resting ankle-arm pressure index in vascular diseases of the lower extremities.

The authors calculated 442 values of resting ankle-arm indices in 222 patients, of whom 114 reported exercise pain of the lower extremities (51.3%) and 34 reported rest pain (15.3%). Tissue necrosis was diagnosed in 55 patients (24.8%) and other disorders in 19 (8.6%). Obliterating atherosclerosis was found in 186 patients (83.8%), Buerger's disease in 16 (7.2%), and other vascular diseases in 20 patients (9%). The studied index value in 262 examined lower extremities was 1.3-1.0 in 54, 0.9-0.8 in 29, 0.7-0.6 in 66, 0.5-0.4 in 55, and 0.3-0.0 in 58 lower extremities. Respective values for contralateral lower extremities (180) were the following: 69, 54, 33, 14, and 10.

Collodion babies with Gaucher's disease.

Two neonates with acute infantile cerebral Gaucher's disease had prominent collodion skin. Ichthyosis has been described in some cases of metabolic lipid disorders, however, this is the first report of the association of lamellar desquamation of the newborn (collodion baby) with Gaucher's disease.
