Steroid responsiveness in a case of Riedel's thyroiditis and retroperitoneal fibrosis

INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 3 2004
P.K. Moulik
Summary Riedel's thyroiditis is a rare chronic inflammatory disease of the thyroid characterised by an invasive fibrotic process. We present a lady with newly diagnosed hypothyroidism, rapidly enlarging hard, fixed goitre, strongly positive thyroid antibodies and raised erythrocyte sedimentation rate (ESR). A tru-cut biopsy confirmed Riedel's struma. Regression of the goitre and reduction of antibody titres occurred after starting prednisolone, which was stopped after 10 months. Six months later, she presented with renal failure due to retroperitoneal fibrosis that was successfully treated by reinstitution of steroids and ureteric stenting. Very high titres of thyroid antibodies and hypothyroidism predating development of goitre suggest coexistence of Hashimoto's thyroiditis and Riedel's thyroiditis. Tru-cut biopsy obviated the need for open thyroidectomy. A predominantly inflammatory as opposed to fibrotic thyroid histology may predict good response to steroids. Relapse following steroid withdrawal may not only be in the thyroid but also at other sites. [source]

Atypical Ductal Hyperplasia in Stereotactic Breast Biopsies: Enhanced Accuracy of Diagnosis with the Mammotome

THE BREAST JOURNAL, Issue 4 2001
Megha Joshi MD
Abstract: There is little literature assessing the incidence of subsequent carcinoma in patients diagnosed with atypical ductal hyperplasia (ADH) by mammotome. We reviewed 216 stereotactic mammotome biopsies (SMBs) and compared the results to the 121 automated tru-cut biopsies (ATC) performed at our breast care center from June 1994 to July 1998. The median age in the mammotome series was 57 years, compared to 56 years in the ATC group. An increase in biopsies for microcalcifications (49% versus 41%) was noted in the SMB series. This was accompanied by an increase in the number of cases with a diagnosis of pure ductal carcinoma in situ (DCIS) (10% versus 4%). Compared to the tru-cut, in which 38% (3 of 8) of the cases diagnosed as atypical hyperplasia (AH) showed DCIS and/or invasive carcinoma on open biopsy, none of the cases diagnosed as AH on mammotome revealed carcinoma on open biopsy. ADH is more accurately diagnosed with SMB than by the ATC method and may not be an indication for subsequent open biopsy. [source]

Adult primary extragonadal germ cell tumors: Treatment results and long-term follow-up

PEDIATRIC BLOOD & CANCER, Issue 1 2003
Argon Andac MD
Abstract Background Primary extragonadal germ cell tumors (PEGCT) are rare neoplasms. They have a poor prognosis, different behavior, and natural course compared to their gonadal counterparts. Both primary and salvage treatment of these tumors constitute a challenge. We retrospectively evaluated the clinicopathologic status, therapeutic implications, and outcome of our patients with PEGCT. Procedure Between 1991 and 2000, 18 patients with PEGCT (median age 31 years; range 17,63), diagnosed with tru-cut biopsy and treated with cisplatin-based chemotherapy, were evaluated in respect to treatment response and outcome. Results Cisplatin-based chemotherapy achieved a complete response rate of 27.8% and a partial response rate of 55.5%. Overall response rate was 83.3%. Only three patients were unresponsive to chemotherapy; an additional six patients with residual mass underwent surgical resection and were rendered disease-free by surgery. The 5-year actuarial event-free and overall survival were 63.4 and 71.3%, respectively. Conclusions The outcomes of our patients with extragonadal primaries including mediastinal localization appear to be slightly better than those previously reported. Multimodality therapy is essential for these patients and given the relatively poor prognosis, prospective trials with large sample sizes, and new treatment approaches to improve outcome are required.
