RESUMO
Myxoinflammatory fibroblastic sarcoma is an ultra-rare tumor type with a prevalence of fewer than two per 100,000 people. The tumor poses a challenge because it can be misdiagnosed as a benign lesion in clinical and radiological investigations, causing serious morbidity in patients. We present the case of a 33-year-old patient who presented with painless hand swelling that was misdiagnosed as lymphaticovenous malformation based on magnetic resonance imaging. The patient underwent surgical excision, and myxoinflammatory fibroblastic sarcoma was diagnosed postoperatively. All surgical interventions failed to achieve negative margin. A decision to start radiotherapy was made, and tissue convergence was done temporally using acellular dermal matrix and split-thickness skin graft. On patient follow-up, the graft had taken well, and the patient was undergoing radiotherapy sessions with a plan for permanent hand reconstruction after negative margins are achieved. Based on this case report, we identified that magnetic resonance imaging is not yet a reliable method to diagnose myxoinflammatory fibroblastic sarcoma. Therefore, implementing a multidisciplinary team approach, a preoperative core needle biopsy, planned surgical intervention, and early involvement of radiotherapy is recommended to minimize morbidity. We strongly urge establishing a sarcoma specialized treatment center in the region to limit patient morbidity.
RESUMO
INTRODUCTION: Papillary carcinoma originating from a thyroglossal cyst is rare and peculiar, with majority of cases detected after surgery. Despite an excellent prognosis, its management remains controversial. Herein, we report the case of a 53-year-old woman who underwent Sistrunk procedure for a thyroglossal duct cyst and was subsequently confirmed to have papillary thyroid carcinoma. PRESENTATION OF CASE: A 53-year-old woman presented with an anterior midline neck mass for 7 years. The patient had no symptoms of hypo-or hyperthyroidism. Additionally, she had no history of compressive symptoms. Neck ultrasound revealed a well-defined 3.5 cm × 2.2 cm × 3 cm-sized cystic lesion inferior to the hyoid bone, with a peripheral solid component. Neck computed tomography revealed a well-defined 3.7 cm × 3.4 cm × 2.7 cm-sized cystic lesion with an enhanced central solid component with focal calcifications, inferior to the hyoid bone, and in contact with the anterior wall of the thyroid cartilage. Sistrunk procedure was performed. The patient was then diagnosed with papillary thyroid carcinoma with TNM stage pT2 and underwent total thyroidectomy as a follow-up procedure. DISCUSSION: Thyroglossal duct cyst carcinoma is usually detected in the fourth decade of life with a higher prevalence in women. Neck ultrasound is performed during the initial radiological workup to assess the cyst and confirm the presence of the thyroid gland. CONCLUSION: The Sistrunk procedure is highly effective in low-risk patients. A more aggressive approach is required for high-risk patients.
RESUMO
Merkel cell carcinoma (MCC) is an uncommon highly aggressive skin malignancy with an increased tendency to recur locally, invade regional lymph nodes, and metastasize distally to lung, liver, brain, bone, and skin. The sun-exposed skin of head and neck is the most frequent site of involvement (55%). We report the case of a 63-year-old Caucasian male patient who presented with a recurrent left inguinal mass for the third time after surgical resection with safe margins and no postoperative radio- or chemotherapy. The presented mass was excised, and pathological diagnosis revealed recurrent MCC. The patient underwent postoperative radiation therapy, and 6 months later, he developed a right groin mass which was resected and pathological diagnosis confirmed metastatic MCC. Six months later, patient developed an oropharyngeal mass which was unresectable, and pathological biopsy confirmed metastatic MCC. Patient was offered palliative radio- and chemotherapy. In this paper, we also present a brief literature review on MCC.
