- Inflammatory myofibroblastic tumor presenting as ileocecal intussusception-A case reportPublication . Paiva, C.; Soares, F.; Correia, R.; Valente, V.INTRODUCTION: Inflammatory myofibroblastic tumor (IMFT) is an uncommon mesenchymal solid tumor commonly documented in children and young adults. It is usually located in lungs however, extrapulmonary involvement has also been reported. Here we report a case of IMFT presenting as an ileocecal intussusception. PRESENTATION OF CASE: A 55-year-old man presented with a two months history of colicky abdominal pain, more intense at the right inferior abdominal quadrant, and unintentional weight loss of 8kg in the previous four months. Computer tomography showed an image of intussusception at the cecum. Colonoscopy demonstrated a pediculated tubular lesion, with the base near ileocecal valve. We performed a right hemicolectomy. Histopathological examination of the tumor revealed an IMFT. DISCUSSION: IMFT usually affects lungs with rare gastrointestinal involvement. Clinical presentation is related with location of the neoplasm. Intussusception in adults presents with non-specific symptoms and classical image signs facilitate preoperative diagnosis. IMFT diagnosis is histopathological which usually implies surgical resection. Complete surgical excision, with microscopically clear margins, is the mainstain of treatment, with virtually no local recurrence or metastasis. CONCLUSION: Gastrointestinal IMFT are rare in the adult population and clinical features depend on its location. Surgical approach with total excision of the neoplasm confirms the diagnosis. Prognosis is good with the main prognostic indicator being the adequacy of the primary excision.
- Parathyroid carcinoma: From a case report to a review of the literaturePublication . Presa-Fernandes, J.; Paiva, C.; Correia, R.; Polónia, J.; Moreira-Costa, A.Parathyroid carcinoma is a rare endocrine malignancy. The reported incidence is from 0.5 to 5% of primary hyperparathyroidism cases in various series. Consideration of parathyroid carcinoma in the differential diagnosis of hypercalcaemic disorders is important because the morbidity and mortality are substantial and the best prognosis is associated with early recognition and surgical resection.
- Single Jejunum Metastasis from Breast Cancer Arising Twelve Years after the Initial TreatmentPublication . Paiva, C.; Garcia, J.; Silva, C.; Araújo, A.; Araújo, A.; Santos, M.Metastatic involvement of gastrointestinal tract from breast cancer is a rare event. We report the case of a 61-year-old woman presenting with bowel obstruction, related to metastasis of a primary breast cancer she had 12 years earlier (a triple-negative invasive ductal carcinoma treated with surgery and chemotherapy). Bowel obstruction was caused by a 20-centimeter tumor in the jejunum, involving also the transverse colon. The patient underwent en bloc resection of tumor with jejunum and transverse bowel segment and received adjuvant chemotherapy with carboplatin and paclitaxel. Twenty months later, she was alive without disease recurrence.
