RESUMO
Ductal adenocarcinoma of the pancreas is a lethal disease. Surgical extirpation only offers the slim chance for long-term survival in localized disease. We report on a 73 year old female patient who initially underwent successful resection of pancreatic adenocarcinoma in May 2005. She was treated with adjuvant chemotherapy with gemcitabine. In October 2010 the patient noticed increasing dyspnea with haemoptysis. She was soon referred to our center. After the diagnosis of pulmonary adenocarcinoma with widespread metastasis, she was treated with systemic chemotherapy. For a period of next three years, she was treated with different chemotherapy regimens due to repeated episodes of tumor progression. To the best of our knowledge after reviewing the literature, this case represents an unusually clinical course with metachronous pulmonary adenocarcinoma arising after treatment of a primary pancreatic cancer after a long latency period.
RESUMO
Background. Sweat gland carcinoma is a rare malignancy with a high metastatic potential seen more commonly in elderly patients. The scalp is the most common site of occurrence and it usually spreads to regional lymph nodes. Liver, lungs, and bones are the most common sites of distant metastasis. Late lung metastasis of sweat gland adenocarcinoma after a time span of 5 years is extremely rare. Aim. We report a patient with late lung metastasis of a primary sweat gland carcinoma 10 years after initial surgical resection. Conclusion. Sweat gland carcinomas are rare cancers with a poor prognosis. Surgery in the form of wide local excision and lymph node dissection is the mainstay of treatment. Late pulmonary metastases with a latency of 10 years have never been reported in the literature. This is the first clinical documentation of late lung metastasis from sweat gland carcinoma with a latency period of 10 years.
RESUMO
A 30-year old woman was referred to our center because of suspicion of a primary lung tumor of the right upper lobe. Histological examination of the lung lesion revealed lung metastasis of a previously treated alveolar soft part sarcoma of the musculus vastus medialis of the right femur, which was resected 20 years ago. Alveolar soft-part sarcoma is a rare malignant tumor that occurs most often in the soft tissue of lower limbs. It is a slow-growing malignant soft tissue tumor arising in muscle tissue, usually in young adults. Due to pleural and extensive mediastinal infiltration with bilateral lung metastases, a systemic treatment with chemotherapy doxorubicin and ifosfamide was initiated. Late metastases from previously treated alveolar part sarcoma should be considered in patients with suspicious lung lesions even if surgical treatment was performed a long time ago.
