Thyroid metastasis after resection of atypical bronchial carcinoid

Abstract

possible complications. However, incomplete resection of the hematoma resulted in uncontrollable bleeding from the subcapsular lesion or recurrence of hematoma within several years in some publications. 2,7 Complete extirpation, including the capsule, would be desired for cure.In our patient acute massive hemoptysis was treated with emergency tracheal intubation, balloon occlusion of the bleeding bronchus, and bronchial artery embolization. In the literature neither massive hemoptysis nor emergency management for chronic expanding hematoma of the thorax has been reported. Because the bleeding spread to the contralateral lung, the operation was intentionally delayed until the remaining lung function recovered. Thereafter, the patient successfully underwent a pneumonectomy with extirpation of the hematoma. Division of the hilum first and sequential distal dissection of the lung and hematoma through a median sternotomy might have worked well for bleeding control. References

A Good Imitator of Medullary Thyroid Carcinoma: Thyroid Metastasis From a Neuroendocrine Tumor

“…In one case, the anatomic pathology report described a MTC, but all samples were negative for calcitonin. Another case presented ectopic adrenocorticotropic hormone production with thyroid involvement and multiple bone and lymph node metastases; this case also showed a rapid growth of the metastatic lesions and required treatment with octreotide LAR to control the symptoms (5)(6)(7)(8)(9).…”

Report of metastatic ileal neuroendocrine tumor to the submandibular gland

“…To our knowledge, metastasis to the salivary glands has not been described in NETs of gastrointestinal origin. Previous cases have reported bronchopulmonary primaries metastasizing to the submandibular [ 10 ], and thyroid glands [ 3 ], as well as metachronous metastasis to the parotid glands, thyroid, lip, and submandibular gland [ 11 ]. Intestinal NETs have been reported to metastasize to the orbits [ 12 ].…”

“…Rare cases of metastasis from bronchopulmonary NETs to the head and neck have been reported, including the parotid glands [ 2 ] and thyroid [ 3 ]. We present the first case of an ileal NET metastasizing to the submandibular gland in a woman with metastatic disease to the liver and carcinoid syndrome.…”

A Practical Diagnostic Approach to Solid/Trabecular Nodules in the Thyroid

“…It is noteworthy that, in a large series of renal cell carcinomas metastatic to the thyroid, up to 36% of cases were discovered as thyroid masses at the initial presentation [36]. Among other malignancies metastatic to the thyroid that might pose a problem in the differential diagnosis with primary ST thyroid nodules, well-differentiated neuroendocrine carcinomas should be taken into consideration [37]. Once a suspect of thyroid metastases is arisen, appropriate immunophenotyping will guide to the proper diagnosis.…”
