ABSTRACT
INTRODUCTION: Follicular thyroid carcinoma (FTC) is the second most common thyroid cancer subtype after papillary thyroid cancer (PTC), and it accounts for approximately 10% of all thyroid cancers, the incidence of distant metastasis in FTC has been reported to be 6-20%, bones and lungs are the most frequent sites of distant metastases. Most occult thyroid carcinomas are papillary carcinoma. CASE PRESENTATION: We describe an extremely rare case of a 74-year-old woman who had a history of right thyroid lobectomy 20 years ago, was referred to our hospital for metastatic thyroid follicular carcinoma to the sacral region confirmed by the biopsy of the sacral mass. The patient was treated by analgesic radiotherapy, surgical totalisation of thyroidectomy, and Radioactive Iodine, with thyroid replacement by levothyroxine. In the follow up we noticed a significant symptom reduction leading to a much better quality of life. CONCLUSION: Increasing importance should be given to rare metastases in DTP patients. Early detection will help in the early diagnosis and treatment of the disease, thereby improving the patient's survival rate and quality of life.
ABSTRACT
INTRODUCTION: and importance: Head and neck paragangliomas are slowly growing benign tumors and they originate from specialized neural crest cells. We report an unusual combined glomus vagal and jugular tumor that was rarely described in the literature to the best of our knowledge. CASE PRESENTATION: A 51 years old female with no pathological history was presented to our ENT department with 6 months' history of a right latero cervical swelling gradually increasing in size associated with a swallowing difficulties and hoarseness. Preoperatively clinical examination had found vagal and hypoglossal nerve paralysis. Cervical CT scan and MRI had shown glomus jugular tumor. The patient underwent a surgical excision with severe swallowing difficulties and facial palsy in the immediate postoperative period with a mild recovery afterwards. CLINICAL DISCUSSION: Paragangliomas of the mesotympanum and jugular foramen most commonly present as a vascular middle ear mass. The most common presenting symptom is pulsatile tinnitus occurring in 80% followed by hearing loss (60%). Dysfunction of cranial nerves traversing the jugular foramen may be commonly encountered with resultant abnormalities of speech, swallowing and airway function. Vagal paragangliomas are the least common of the three primary craniocervical paragangliomas. The most common presenting sign is the presence of a painless neck mass accompanied occasionally by dysphagia and hoarseness. The association of both glomus vagal and jugular tumor is rarely described in the literature to the best of our knowledge. CONCLUSION: Head and neck paragangliomas are slowly growing benign tumors and they originate from specialized neural crest cells. Vagal paragangliomas are the least common of the three primary craniocervical paragangliomas. The association of both glomus vagal and jugular tumor is rarely described in the literature to the best of our knowledge. The choice of treatment depends on the location, size, and also biologic activity of the tumor as well as the physical condition of the patient.
ABSTRACT
INTRODUCTION: Rhabdomyosarcoma (RMS) is a malignant mesenchymal neoplasm uncommon in adults. PRESENTATION OF CASE: We report the case of an alveolar rhabdomyosarcoma in a rare location and in an adult. It concerns a 46-year-old woman with a mandibular location invading the parotid gland. The Immunohistochemical analysis revealed intense positivity for myogenin and desmin, favoring the diagnosis of alveolar rhabdomyosarcoma. The patient had a right hemi-mandibulectomy with parotidectomy and received chemotherapy with radiotherapy. The evolution was good up to 2 years postoperatively then the patient relapsed with a recurrence of tumour rapidly progressing and metastases in the cervical spine. DISCUSSION: RMS is an aggressive but rare disease that is one of the most common malignant head and neck tumors in children. The predilection sites of adult rhabdomyosarcoma are the extremities. Current treatment includes a combination of ablative surgery, chemotherapy, and radiation therapy. CONCLUSION: The prognosis of head and neck rhabdomyosarcomas in adults remains very poor given the often initially advanced stage of the disease and the high metastatic potential.
