Synchronous intrathyroidal parathyroid carcinoma and thyroid carcinoma: case report and review of the literature.

BACKGROUND: Parathyroid carcinoma is a rare endocrine malignancy, rarer when synchronous with a non medullary well differentiated thyroid carcinoma. Parathyroid carcinoma accounts of 0.005% of all malignant tumors and it is responsible for less than 1% of primary hyperparathyroidism. The intrathyroidal localization of a parathyroid gland is not frequent with a reported prevalence of 0.2%. Carcinoma of parathyroids with intrathyroidal localization represents an even rarer finding, reported in only 16 cases described in literature. The rare constellation of synchronous parathyroid and thyroid carcinomas has prompted us to report our experience and perform literature review. CASE PRESENTATION: We herein report a case of a 63-years-old man with multinodular goiter and biochemical diagnosis of hyperparathyroidism. Total thyroidectomy with radio-guide technique using gamma probe after intraoperative sesta-MIBI administration and intraoperative PTH level was performed. The high radiation levels in the posterior thyroid lobe discovered an intrathyroidal parathyroid. Microscopic examination revealed a parathyroid main cell carcinoma at the posterior thyroidal left basal lobe, a classic papillary carcinoma at the same lobe and follicular variant of papillary carcinoma at the thyroidal right lobe. To the best of our knowledge, this is the first case documenting a synchronous multicentric non medullary thyroid carcinomas and intrathyroidal parathyroid carcinoma. CONCLUSIONS: Our experience was reported and literature review underlining challenging difficulties in diagnostic workup and surgical management was carried out.

Breast conserving treatment for ductal carcinoma in situ in the elderly: can radiation therapy be avoided? Our experience.

INTRODUCTION: Ductal Carcinoma In Situ (DCIS) is a heterogeneous, pre-malignant disease accounting for 15-20% of all new breast cancers. If appropriately managed, DCIS has a small chance of impacting on patient life expectancy. Despite the possibility of a further recurrence or of a development in an invasive form, we are unable to select treatment of choice especially in the elderly. In particularly we risk an overtreatment of women at low risk of progression to invasive breast cancer. The aim of this study was to retrospectively evaluate the outcome of elderly patients affected by DCIS not undergoing Radiation Therapy (RT) after Breast Conserving Surgery (BCS). MATERIAL AND METHODS: We reviewed our prospectively-maintained database from 1998 to 2013, selecting all women over 65 years old diagnosed with DCIS who did not receive RT for personal choice. We considered two groups, according to the risk of local recurrence (Low Risk (Group 1) vs. High Risk (Group 2)). RESULTS: We identified 44 cases of DCIS treated with surgery alone or with surgery followed by adjuvant tamoxifen. 24 patients presented low risk of local recurrence (Group 1) and 20 had characteristics associated to high risk of local recurrence (Group 2). At a median follow-up of 66.3 months, no local recurrences have been described in group 1. No patients presented distant metastases, while 4 patients died for other causes. At a median follow-up of 72 months we observed 5 local recurrences in the second group (p < 0.05). CONCLUSION: Our results suggest that radiation therapy can be safely avoided in a selected group of elderly patients affected by DCIS.

Axillary masses in a woman with a history of breast cancer: dermatopathic lymphadenopathy.

The presence of axillary enlarged lymph nodes in the follow-up of a woman with a history of breast cancer should always be thoroughly indagated. Dermatopathic lymphadenopathy presents a specific pathologic pattern found within the lymph nodes and is usually associated with cutaneous rashes. Patients with various skin conditions can develop regional lymphadenopathy, which can result in the asymptomatic enlargement of the lymph nodes, especially in the inguinal, axillary and cervical regions. Dermatopathic lymphadenopathy should be considered in the differential diagnosis also in patients with minimal cutaneous findings. Dermatopathic lymphadenopathy is a benign process and management of these patients consists in simple clinical, mammographic and ultrasonographic follow-up.
