RESUMO

Background: Myxopapillary ependymoma is a rare type of primary spinal tumor, it is distinctly a slow-growing tumor that originates in the conus medullaris, cauda equina, or film terminals and is rarely identified as a multicentric type. Myxopapillary ependymoma has a unique histological characteristic and is associated with a generally better prognosis. Objective: We present a case of a rare multicentric myxopapillary ependymoma. Case presentation: A 28-year-old male with 1-year history of low back pain and 3 months of radiating pain to left lower limb with perianal anesthesia. Magnetic resonance imaging (MRI) exhibited a large intradural intramedullary lesion from the level of the conus medullaris extending to the filum terminals at the level of T12 to L3 with smaller multiple enhancing lesions seen opposite to L4 and L5 level as well as within the exiting nerve roots, at the left side of L1/L2 and L2/L3 and right side of L3/L4 and L5/S1 level. The patient underwent surgical resection with significant improvement in symptoms and no tumor progression on follow up MRI scan. Conclusion: We hereby present a case of multicentric myxopapillary ependymoma with a literature review of the previous reported cases. We believe that our study will make a significant contribution to the literature and will be of interest to the readership regarding of the rarity of multicentric Myxopapillary ependymoma and it will help in decision making for the proper surgical Intervention on these kinds of cases.

RESUMO

BACKGROUND: Adenomyoepithelioma of the breast is an uncommon subtype of breast neoplasm that occurs in adults over a wide age range but most commonly in middle-aged and older adults. It usually presents as a solitary palpable mass or is detected on breast radiographic images. Histologically, it is a biphasic tumor with proliferation of both the epithelial and myoepithelial components of the glands, with variable types of tissue metaplasia. CASE PRESENTATION: A 64-year-old Saudi woman who underwent regular breast screening (mammogram) presented to our hospital following radiographic detection of a suspicious grouped microcalcification in the upper outer quadrant of her right breast on the mammogram. A wide local excision of the right breast lump was performed. Following histopathological examination of the breast lump, the final diagnosis was breast adenomyoepithelioma with mucoepidermoid/divergent differentiation, with no evidence of malignancy. About two years after the operation, a clinical follow-up conducted outside our hospital showed the development of ductal carcinoma in situ in the same breast. CONCLUSION: Although the prognosis and the plan of treatment remains the same, our case highlights the complexities in making an accurate diagnosis between the various types of metaplasia within adenomyoepithelioma on one hand and the presence of mucoepidermoid differentiation in adenomyoepithelioma on the other.

RESUMO

BACKGROUND Diverticulosis of the vermiform appendix is rare. In patients who present with appendicitis, appendiceal diverticulitis as a cause due is also rare. We report the case of a 35-year-old man who presented with typical symptoms and signs of acute appendicitis, which was confirmed by histopathology to be due to perforated acute appendiceal diverticulitis. CASE REPORT A 35-year-old man presented to our Emergency Department with a 1-day history of right lower-quadrant abdominal pain that radiated to the left lower quadrant, which was associated with fever, vomiting, and abdominal distention. Biochemical analysis revealed mild leukocytosis. Computed tomography (CT) revealed signs of acute perforated appendicitis and early mass formation. The patient underwent laparoscopic appendectomy. Histopathological examination revealed appendiceal diverticulitis (pseudo-diverticulum). CONCLUSIONS Appendiceal diverticulitis is a rare surgical entity and is often an overlooked diagnosis. The differential diagnosis of appendiceal diverticulitis in patients presenting with signs of acute appendicitis is important as it is associated with a higher rate of complications such as perforation and an increased risk of appendiceal neoplasms. Appendectomy is a safe and appropriate treatment for appendiceal diverticulitis.
