A 25-year-old woman presented with a 4 months history of progressive pain and tumefaction in the right parietal region. Deformity of the scalp was evident, and a biopsy was taken, reporting a high- grade dermatofibrosarcoma. She underwent surgical management, achieving a gross total resection. Dermatofibrosarcoma protuberans is a rare tumor arising from the dermis. It tends to have an indolent course and local recurrence after excision.

Adnexal Tumors

Porocarcinomas are aggressive adnexal tumors with a rare incidence. They are usually seen as a nodular or infiltrating growth over the lower extremities, infrequently over the scalp. They are thought to be arising from a pre-existing lesion and with a long clinical history. Treatment of choice is surgical resection with histopathologically confirmed negative margins. There are chances of local recurrence; hence a regular follow-up is must in these cases. Hereby we present a case of 42 year old male with 2 year history of growth over the right temporo-parietal region of the scalp. Histological confirmation of the diagnosis was done after wide local excision of the tumor. Porocarcinomas are mostly likely to be misdiagnosed clinically; therefore a histopathological correlation is necessary for the confirmation of diagnosis and further management of the patient.

Although, gross total resection in large vestibular schwannomas is an ideal goal, subtotal resection is frequently performed due to lack of expertise, concerns for facial palsy, or overuse of stereotactic radiation. In this video, we present a 31-year-old man with a 7-year history of tinnitus, dizziness, and hearing loss. The patient had a subtotal resection of a 2.5 cm right-sided vestibular schwannoma via retrosigmoid craniotomy at an outside hospital. He was referred for further surgical resection due to the increased size of the tumor on surveillance magnetic resonance imagings (MRIs) and worsening symptoms. MRI showed a residual/recurrent large schwannoma with extension to the full length of the internal acoustic canal and brain stem compression. He underwent microsurgical gross total resection via a translabyrinthine approach. The facial nerve was preserved and stimulated with 0.15 mA at the brainstem entry zone. He awoke with House–Brackmann grade III facial function, with an otherwise uneventful postoperative course. In this video, microsurgical techniques and important resection steps for this residual/recurrent vestibular schwannoma are demonstrated, and nuances for microsurgical technique are discussed.The link to the video can be found at: https://youtu.be/a0ZxE41Tqzw.

Introduction. Primary hypopharynx involvement of small cell carcinoma is very rare and very few cases have been reported in the literature. Here, we report a case of primary small cell carcinoma of the hypopharynx in a male patient.Case Report. A 50-year-old man presented with a 6-month history of sore throat and swellings in the right side of the neck. Direct laryngoscopy and biopsy revealed small cell carcinoma of the hypopharynx located in the right pyriform sinus.Discussion. Small cell carcinoma of the hypopharynx has no clear treatment modality due to the rarity of the disease. Systemic chemotherapy and radiotherapy should have priority among the therapy regimens because of the high metastatic potential of the tumor.

Nodular lymphocyte-predominant Hodgkin lymphoma is an uncommon variant of Hodgkin lymphoma. Progressive transformation of germinal centers has been associated with and can develop prior to, concurrent with, or after the diagnosis of nodular lymphocyte-predominant Hodgkin lymphoma. We present a patient with a history of progressive transformation of germinal centers of the right parotid who presented 4 years later with ipsilateral parotid mass and cervical adenopathy. Knowledge of her previous diagnosis raised our concern for lymphoma, influenced our surgical management, and spared the patient additional surgery with risk of facial nerve injury inherent in revision parotidectomy.

Combined pleomorphic xanthoastrocytoma (PXA) and ganglioglioma (GG) is an extremely rare tumor, with fewer than 20 cases reported. The authors report a case of combined PXA-GG in an 18-year-old man with a history of seizures. The tumor showed necrosis and the BRAF V600E mutation on histological examination, with no evidence of tumor recurrence 1 year after gross-total resection. The BRAF V600E mutation was present, which suggests that both cell lineages may share a common cellular origin.

Malignant Triton Tumour

A 65-year-old female patient has a history of malignant triton tumour of the right upper lobe of the lung. She underwent right upper lobectomy and lymphadenectomy in May 2018. She presented in November 2019 with pathological fracture of the left proximal femur. It was not associated with neurofibromatosis. We decided to do an excisional biopsy of the mass and proximal femoral replacement followed by radiotherapy. Four months later, she presented with local recurrence. We organised a multidisciplinary team between the orthopaedic, histopathology and oncology teams. Then, we decided to treat her with chemotherapy. After 2 months of follow-up, she responded well to the chemotherapy with no further deterioration of her condition.

Pleomorphic Sarcoma

Primary pleomorphic sarcoma of the left atrium is a rare tumor. There is no actual evidence of the management of this pathological entity, so the main treatment is individualized, surgical management being the cornerstone of the treatment. We present a 78-year-old female who had a clinical picture of heart failure, documenting an atrial mass of the left atrium, with high-grade pleomorphic sarcoma revealed in histopathology. The tumor was surgical removed, with no clinical evidence of residual mass. The tumor recurred again within 3 years, to which the patient succumbed.

This 40-year-old man presented with a 5-month history of progressive right-sided headache associated with visual blurring. He also had a history of epilepsy but had been seizure free with medication for the past 10 years. An initial CT scan of his brain performed 16 years previously had revealed a small area of calcification in the right parietal region. In the current presentation, he had a left-sided homonymous hemianopia but no other neurological deficits. A CT scan of his brain showed a much larger calcified, partly cystic lesion in the right parietal region. Because he was symptomatic, the lesion was excised and the cyst was drained. Histological examination of the excised tissue showed an unusual primary tumor that was difficult to classify but had some features of angiocentric glioma. The heavy calcification, mixed-density cell population, and regions with features of angiocentric glioma were most unusual. The patient remained asymptomatic 5 years after surgery, and follow-up scans did not show recurrence.

Abstract BACKGROUND: Gangliogliomas are rare glioneuronal tumors that typically cause refractory seizures during the first 3 decades of life. OBJECTIVE: To determine the prognosticators of seizure outcome after surgery for ganglioglioma. METHODS: We reviewed the cases of 66 patients who underwent resection of gangliogliomas at the University of California, San Francisco. Demographic, seizure history, and operative data were examined for statistical association with postoperative seizure outcomes. RESULTS: Of the 66 patients who underwent surgical resection of ganglioglioma, 49 patients (74%) presented with a history of seizures. Of those 49 patients, 50% presented with intractable epilepsy. Temporal lobe gangliogliomas were present in 76% of the patients who presented with a history of seizures. Electrocorticography was performed on 35% of the patients, and of those patients, 82% underwent extended lesionectomy to remove abnormally epileptogenic extralesional tissue. The median follow-up duration was 6.9 years, during which tumor progression occurred in 38% of patients who underwent subtotal resection and in 8% of patients who underwent gross total resection (P = .02). Overall, 85% of patients were seizure free (International League Against Epilepsy class I or II) 5 years after surgery. Subtotal resection was associated with poor seizure outcomes 1 year after resection (odds ratio = 14.6; 95% confidence interval = 2.4-87.7): rates of seizure freedom were 54% after subtotal resection, 96% after gross total resection, and 93% after gross total resection with intraoperative electrocorticography-guided extended lesionectomy. CONCLUSION: We report excellent long-term seizure control outcomes after surgery for gangliogliomas. Intraoperative electrocorticography may be a useful adjunct for guiding extended resection in certain pharmacoresistant epilepsy patients with gangliogliomas. Subtotal resection is associated with higher rates of tumor progression and nonoptimal seizure outcomes.
