Discontinuous appendiceal involvement in ulcerative colitis: pathology and clinical correlation.

Continuous mucosal involvement from the rectum proximally is one of the hallmarks of ulcerative colitis. However, recent pathologic series report appendiceal ulcerative colitis in the presence of a histologically normal cecum, representing a "skip" lesion. The clinical significance of this finding has not been established. Eighty patients, 54 males and 26 females, average age 37.9 years (range 14 to 82 years) who underwent proctocolectomy for ulcerative colitis from January 1990 to September 1995 were examined to determine the rate of discontinuous appendiceal involvement. Excluded were 12 patients with prior appendectomy and 11 with fibrotic obliteration of the appendiceal lumen. Of the remaining 57 patients, seven (12.3%) had clear appendiceal involvement in the presence of a histologically normal cecum. These seven patients clinically were indistinguishable from the 50 patients without skip involvement of the appendix in terms of age at surgery, pretreatment medications, type of surgery, interval from diagnosis to definitive procedure, complications, functional results, and clinical course. Discontinuous appendiceal involvement was found in 12.3% of patients undergoing proctocolectomy for ulcerative colitis, and clinically these patients behave as those without this feature.

Biopsy technique has no impact on local recurrence after breast-conserving therapy.

Image-guided core needle breast biopsy (IGCNBB) is an incisional biopsy technique that has been associated with tumor cell displacement. Theoretically tumor cell displacement may affect local recurrence rates in patients treated with breast-conserving therapy (BCT). We performed a study to determine if the biopsy method impacted local control rates following BCT. Patients with nonpalpable breast cancer (invasive and intraductal) diagnosed at our institution and treated with BCT between July 1993 and July 1996 were selected to provide a follow-up period in which the majority of local recurrences should be detected. Patients were divided into two groups based on their method of diagnosis. Group I patients were diagnosed by IGCNBB and group II patients were diagnosed by wire localized excisional breast biopsy (WLEBB). Factors potentially affecting local recurrence rates were retrospectively reviewed. Two hundred eleven patients were treated with BCT, 132 were diagnosed by IGCNBB and 79 by WLEBB. The two patient groups were similar when compared for prognostic factors and treatment. All patients' BCT included histologically negative margins. There were 4 (3.0%) local recurrences in Group I at a median follow-up of 44.4 months and 2 (2.5%) local recurrences in group II at a median follow-up of 50.1 months. This difference was not significant. Breast cancer patients diagnosed by IGCNBB can be treated by BCT with acceptable local control rates. Additional surveillance of our institutional experience and others' is mandatory to validate IGCNBB as the preferred biopsy method for nonpalpable mammographic abnormalities.

Chondrosarcoma of the larynx: excision of massive recurrence.

Chondrosarcoma of the larynx is an uncommon, slow-growing malignant tumor of the larynx which tends to metastasize late. This paper adds to the literature a case which was followed for 18 years. During the first three years it was thought to be a benign chondroma. Conservative management by limiting surgical resection, at the patient's direction, allowed observation of the disease for this unusual length of time. Massive enlargement finally necessitated laryngectomy. The lesion, though unquestionably malignant, had not infiltrated adjacent neck structures and appears to have been totally excised, with the patient now being free of disease six months after surgery. This supports the view of conservative surgical management.
