ABSTRACT
The purpose of this publication is to report a child with choroidal metastasis from a primary lung carcinoid tumor treated with 125-iodine plaque brachytherapy while achieving complete tumor regression. A 15-year-old girl with a history of stage IV lung carcinoid tumor developed painless progressive visual loss in her right eye. Ophthalmological exam documented a unilateral solitary large choroidal mass with complete exudative retinal detachment. Planned palliative treatment with plaque brachytherapy was performed utilizing a total dose of 45 Gy to the tumor apex. No tumor regression was noted after 6 months of follow-up. Ten months after primary therapy, re-treatment with a total dose of 90 Gy to the tumor apex was performed due to tumor progression. Complete regression was achieved after secondary treatment without evidence of recurrence after 18 months of follow-up. In conclusion, high-dose plaque brachytherapy may induce complete tumor regression in select adolescent patients with choroidal metastasis from lung carcinoid tumor.
ABSTRACT
Clear cell carcinoma of the lung is very rare, with few cases reported in the medical literature. Review of case studies show that these tumors have significant variation in clinical outcome, including metastatic disease. We present a very unusual case of primary clear cell lung carcinoma of salivary gland type.

OBJECTIVE: Primary cardiac tumors are rare neoplasms in humans, of which the most common is the atrial Myxoma. The objective of this study was to find the incidence of these tumors at the Heart Center of Puerto Rico and the Caribbean. METHODS: This study was approved by the Institutional Review Board of the Medical Sciences Campus University of Puerto Rico to review the records at the Heart Center of patients with heart tumors in the last 14 years. RESULTS: The sample consists of 55 patients (78.9% were females and 24.1% were male) with a median age of 52 years. Sixty-five percent of patients lived in rural areas. Clinical presentations included shortness of breath (43.1%), chest pain (37.9%), asymptomatic (25%), palpitations (20.7%), neurologic symptoms (10.3%) and dizziness (6.9%). Electrocardiographic findings included normal sinus rhythm (53.4%), non-specific ST-T changes (32.8%), sinus tachycardia (20.7%), left atrial enlargement (10.3%) and atrial fibrillation (8.6%). A subgroup presenting with atrial fibrillation prior to diagnosis had left atrial myxoma. The tumors found, in descending order of frequency are: left atrial myxoma, right atrial myxoma, papillary fibroelastoma, hamartoma, lipoma and rhabdomyoma. We found a correlation between large left atrial myxoma and atrial fibrillation. CONCLUSION: The most frequent heart tumor was atrial myxoma. The larger myxomas were associated with atrial fibrillation.
