Aggressive angiomyxoma is a mesenchymal tumor arising from connective tissues with a predilection to the female pelvic soft parts. Cervico-facial localization remains rare .We report here the first case of aggressive angiomyxoma of the external ear of a 7 year old patient, which was treated successfully by surgical excision. The clinical and pathologic features and radiological aspects of this tumor are discussed.

AbstractAggressive angiomyxoma (AAM) is an uncommon mesenchymal tumor that predominantly involves the pelvis and perineum of young females. It is often clinically mistaken for more common superficial lesions such as vaginal cysts, labial cysts, and lipomas. A review of the medical literature reveals very few cases of AAM reported in pregnancy. We describe a rare case of AAM in pregnancy, clinically misdiagnosed as prolapsed cervical fibroid.

Rare Case Report

Abstract Background Aggressive angiomyxoma (AA) is a rare tumor that typically occurs in the pelvis and perineum, most commonly in women of reproductive age. However, no para-ureteral AA has been reported according to the literature. Case presentation We herein describe the first case of para-ureteral AA. A 62-year-old male presented to our institute in March 2017 with a para-ureteral mass that was 15 mm in diameter incidentally. No symptom was observed and laboratory analysis was unremarkable. Magnetic resonance and computed tomography imaging showed a non-enhancing mass abutting the left ureter without causing obstruction. Laparoscopic resection of the mass was performed without injury to the ureter. Pathologic and immunohistochemical results were consistent with AA. Till now, no recurrence was noticed. Conclusions We reported a rare case of para-ureteral AA, along with a literature review. Early diagnosis, proper surgical plan and long-term close follow-up is recommended for its high risk of recurrence and malignant potential.

Aggressive angiomyxoma (AA) is a rare, locally infiltrating soft tissue tumor typically located in the genital tract of young, reproductive age women. Surgical excision has been the mainstay of treatment. Recently, gonadotropin-releasing hormone agonist therapy has been reported to decrease the size of estrogen-receptor positive AA. We present the first case of a postmenopausal woman treated with an aromatase inhibitor to shrink the size of tumor prior to surgical resection.

Dermatofibrosarcoma protuberans is a rare, slow-growing, locally destructive, intermediate-grade malignancy that originates in the dermal layer of the skin. Dermatofibrosarcoma protuberans rarely metastasizes and has a marked tendency to recur following local surgical excision. The lesion is found most commonly on the trunk, on the proximal aspect of both the lower and upper extremities, and in the head and neck region. Dermatofibrosarcoma protuberans occurs most commonly in people between the ages of 20 and 50. This article describes the clinical and pathologic features of this rare, malignant neoplasm and describes a rare case of dermatofibrosarcoma protuberans involving the pediatric foot.

Vulvar aggressive angiomyxoma (AA) is a rare mesenchymal tumor of the vulva. Due to its slow-growing nature, it is often overlooked and misdiagnosed by primary care providers (PCPs). We describe a case report of vulvar AA in a 38-year-old woman who underwent complete surgical excision of the neoplasm with no evidence of recurrence on a 5-year followup. A literature review follows to provide PCPs with the clinical, radiologic, and pathologic features that this tumor displays.

Upbeat Nystagmus

Abstract Introduction CNS cavernomas are a type of raspberry-shaped vascular malformations that are typically asymptomatic, but can result in haemorrhage, neurological injury, and seizures. Here, we present a rare case of a brainstem cavernoma that was surgically resected whereafter an upbeat nystagmus presented postoperatively. Case report A 42-year old man presented with sudden-onset nausea, vomiting, vertigo, blurred vision, marked imbalance and difficulty swallowing. Neurological evaluation showed bilateral ataxia, generalized hyperreflexia with left-sided predominance, predominantly horizontal gaze evoked nystagmus on right and left gaze, slight left labial asymmetry, uvula deviation to the right, and tongue deviation to the left. MRI demonstrated a 13-mm cavernoma with haemorrhage and oedema in the medulla oblongata. Surgery was performed via a minimal-invasive, midline approach. Complete excision was confirmed on postoperative MRI. The patient recovered well and became almost neurologically intact. However, he complained of mainly vertical oscillopsia. The videonystagmography revealed a new-onset spontaneous upbeat nystagmus in all gaze directions, not suppressed by fixation. An injury of the rarely described intercalatus nucleus/nucleus of Roller is thought to be the cause. Conclusion Upbeat nystagmus can be related to several lesions of the brainstem, including the medial longitudinal fasciculus, the pons, and the dorsal medulla. To our knowledge, this is the first case of an iatrogenic lesion of the nucleus intercalatus/nucleus of Roller resulting in an upbeat vertical nystagmus. For neurologists, it is important to be aware of the function of this nucleus for assessment of clinical manifestations due to lesions within this region.

Most malignant tumors of the penis are squamous cell carcinomas (SCC), being divided in 2 groups, one human papillomavirus (HPV)-related and another non-HPV-related, with lymphoepithelioma-like carcinoma (LELC) being one of the rarest HPV-related SCC. In this article, we report a case of a 50-year-old man who presented testicular swelling and pain for the past 3 months. A penile mass was identified, and the patient was submitted to a total penectomy. The penectomy specimen showed an ulcerated lesion at the glans reaching the cavernous bodies. Microscopic examination showed undifferentiated epithelial cells with syncytial growth pattern mix with a dense lymphoplasmacytic infiltrate, consistent with LELC. The tumor cells expressed p16 and all 3 different clones of PDL1 (22C3, SP263, and SP142). The patient is alive and well with a follow-up of 3 months. To our knowledge, this is the third LELC of the penis reported in literature and the first case reported with PDL1 expression.

Neural Sheath

Schwannoma or neurilemmoma is a common soft tissue neoplasm arising from the neural sheath of Schwann cells. However, intraosseous schwannoma is rare, accounting for less than 0.2% of primary bone tumours. Several variants of schwannoma have been reported; among them, intraosseous schwannoma with ancient change is extremely rare. This current report presents an extremely rare case of ancient intraosseous neurilemmoma. The patient presented with right elbow pain and disability. A radiolucent, well-defined, lobulated lesion with a thin sclerotic rim in the proximal ulnar metaphysis that had caused a pathological fracture was noted. The mass was surgically excised using marginal resection and bone curettage was undertaken. The bone deficit was grafted with hydroxyapatite and β-tricalcium phosphate and augmented with bone cement. There were no signs of any recurrence after 3 years. This is the first case of an ancient intraosseous schwannoma of the proximal ulna. Although rare, intraosseous schwannoma should be considered in the differential diagnosis of radiographically benign-appearing osseous tumours in the bone. The cement technique is recommended for the treatment of intraosseous schwannoma.

AbstractPrimitive neuroectodermal tumors (PNET) are very rare tumors that belong to a family of malignant neoplasms of tiny round cells which are derived from the neural crest. This report discusses a rare case of an adult woman with esophageal PNET, confirmed by immunohistochemistry, that presented with metastasis to the pineal gland. To our knowledge, this is the first case report of a PNET with these features. Despite surgery and chemotherapeutic treatment, our case has shown disease progression.
