Semimembranosus ganglion cyst / 대한해부학회지

Ganglion cysts are tumor-like lesions in the soft tissues, generated by mucoid degeneration of the joint capsule, tendon or tendon sheaths on the dorsum of hand, wrist and foot. However, an intratendinous origin for a ganglion cyst is extremely rare. During dissection of the popliteal fossa, a cyst of 2.5 cmx2 cmx0.5 cm was observed in the tendon of right semimembranosus, 3.5 cm above the insertion of the muscle. Contrast X-ray revealed the cyst as not communicating with the knee joint or any adjacent bursae. Histopathological examination confirmed the diagnosis of ganglion cyst.

Abdominal tuberculosis may masquerade many diseases

Intestinal tuberculosis needs to be considered in the differential diagnosis when patients with intestinal pathology are encountered. Tuberculosis can mimic other disease entities like, ischemic enteritis, inflammatory bowel diseases, malignancies, intussusception etc., clinically as well as morphologically in resected intestinal specimens. We aimed to study the various clinical presentations leading to intestinal resection, with identification of different etiological factors by histopathological examination; and to illustrate, discuss and describe the various histopathological features of the lesions in these resected intestinal specimens with clinicopathological correlation. We studied 100 cases of resected intestinal specimens received during September 2002 to December 2003. We totally encountered 22 request forms with clinical suspicion of ileoceocal tuberculosis. Abdominal tenderness and mass in ileoceocal region were noted in all cases. In many instances, the cases were operated for acute/subacute intestinal obstruction. Clinical and intra-operative diagnoses of tubercular enteritis, in many instances, were finally diagnosed histopathologically as ischemic enteritis [nine cases], chronic nonspecific enteritis [four cases], adenocarcinoma of the caecum, Crohn's disease, intussusception [each one case], and correctly as intestinal tuberculosis in only six cases. Tuberculosis can mimic various disease entities, clinically and sometimes morphologically. Vice versa is also true. An increased awareness of intestinal tuberculosis coupled with varied clinical presentations, nonspecific signs and symptoms, difficulties in diagnostic methods and need of early and specific treatment should improve the outcome for patients with this disease

"MacCallum plaque of the heart": a medicolegal case

Mural endocardial lesions can be seen as MacCallum plaques in rheumatic heart disease. These plaques appear as map-like areas of thickened, roughened, and wrinkled part of the endocardium in the left atrium. Perhaps they are caused by regurgitant jets of blood flow, due to incompetence of the mitral valve. Although MacCallum plaques are one of the characteristic features in rheumatic heart disease, they are very uncommon in recent times. We hereby report a case of an adolescent female with RHD, who was working as a housemaid in a doctor's house for a few months, and suddenly developed respiratory tract infection and cardiac failure. She died on the fourth day of admission. A medicolegal autopsy was conducted, as her relatives accused her master of sexual assault. On autopsy it was seen that the mitral valves were narrowed, showing multiple vegetations. MacCallum plaque was seen in the dilated left atrium. Hence, it is presented here for educative purposes
