[Rare entity of a macroscopically visible tumor cone of squamous cell carcinoma in the greater veins of the head and neck].

Cones of malignant tumors are commonly known but only a few descriptions of cones in the head and neck area exist - as seen in a 91-year-old patient under our care. Cones of thymic and thyroid cancers are described in the literature. There are no descriptions of cones of head and neck squamous cell carcinomas. Metastases of squamous cell carcinoma in the head and neck area are very aggressive and have a high potential for vascular neogenesis. A vascular cone might be possible by vascular formation or by mechanical intrusion as described elsewhere.

[Spontaneous infrapatellar tendon rupture in a patient with systemic lupus erythematosus].

A case is described of a 33-year old woman with systemic lupus erythematosus (SLE) in longterm treatment with corticosteroids who experienced spontaneous rupture of the left patellar tendon. A comparative study of 28 previously reported cases of SLE patients with spontaneous tendon rupture in weight bearing joints is performed. It is suggested that renal disease may be an etiological factor for spontaneous tendon rupture in patients with systemic lupus erythematosus.

[Chronic compartment syndrome in the lower leg].

Chronic compartment syndrome (CCS) is characterized by recurrent pain in and functional disability of affected muscles, and is typically encountered in the lower leg. The condition is due to physical activity causing an increased intracompartmental pressure (ICP), which subsequently impedes blood flow and thereby compromises the metabolic demands of the tissues within the compartment. After ceasing of activity the symptoms gradually disappear. The incidence of CCS is uncertain. Diagnosis can be established by measuring the ICP before and after relevant physical activity. Treatment is either restriction in activity or fasciotomy, which in most cases is curative.

Human pulmonary dirofilariasis.

A case of human pulmonary dirofilariasis is reported. This human infestation must be considered in the differential diagnosis of a pulmonary "coin" lesion, which lies adjacent to a pleural surface, especially where tissue sections reveal a pulmonary infarct.

Cytologic criteria for subclassification of Hodgkin's disease using fine-needle aspiration.

Hodgkin's disease (HD) is increasingly being evaluated by fine-needle aspiration (FNA); however, criteria to subclassify HD into its four subtypes--nodular sclerosis (NS), mixed-cellularity (MC), lymphocyte-depleted (LD), and lymphocyte-predominant (LP)--has not been established. In order to evaluate criteria for subclassification, all FNA cases of HD obtained over a 5-yr period at Indiana University Medical Center that had confirmatory surgical biopsies were reviewed. The number of Reed-Sternberg (RS) cells was quantitated in each cytologic case and statistically analyzed by subgroup, using analysis of variance (ANOVA). LD had the highest mean (means) number of RS cells (means = 51) with NS and MC having similar means (means = 7 and 6, respectively). Only one case of LP was identified and therefore could not be analyzed statistically. Fibrosis and the presence of RS variants were qualitatively assessed and were not helpful in distinguishing the subtypes of HD. Although the quantitation of RS cells may be used to identify LD types of Hodgkin's disease, MC and NS cannot be separated reliably on this criterion alone. Although FNA can be used to diagnose HD, stage a patient, or assess efficacy of chemotherapy, subtyping of HD should still be done on histologic sections of excised lymph nodes.

Osteosarcoma of the uterine cervix associated with hyperplastic and atypical mesonephric rests.

The authors describe a unique case of osteosarcoma associated with atypical mesonephric rests occurring in the right lateral wall of the uterine cervix. The tumor was examined histologically, cytologically, immunohistochemically, and ultrastructurally and was compared with another osteosarcoma that filled an entire uterine cavity. Comparison with other neoplasms of the uterine cervix indicates that the lesion should be classified separately. Previously reported neoplasms associated with mesonephric rests within the cervix are also reviewed.

Testicular papillary cystadenomatous tumor of low malignant potential: a case report and discussion of the literature.

We report the fifth case of a rare testicular serous papillary cystadenomatous tumor of low malignant potential. All patients presented with a testicular mass. Histologically, the tumor can be differentiated from testicular papillary cystadenocarcinoma. The natural history of this rare tumor is yet to be determined.
