Primary pineal malignant melanoma is a rare entity, with only thirteen cases reported in the world literature to date. We report a case of a 70-year-old man, who consulted with gait disturbance of six months duration, associated in the last month with dizziness, visual abnormalities and diplopia. No other additional melanocytic lesions were found elsewhere. The magnetic resonance showed a 25 mm expansive mass in the pineal gland that was associated with hydrocephaly, ventricular and transependimary oedema. The lesion was partially excised by a supracerebellar infratentorial approach. The histological examination revealed a melanoma. The patient received radiation therapy, but died of disease 16 weeks later. We herein review the literature on this rare tumour and comment on its clinical, radiological and histopathological features and differential diagnosis.

Sinonasal glomangiopericytoma is a rare sinonasal tumour accounting for less than. 5% of all sinonasal tumours. This tumour often presents as another, more common type of vascular lesion and is similarly prone to haemorrhage. The optimal treatment includes complete surgical resection. We, herein, present two such cases adding to the world literature of this rare tumour.

AbstractObjective:We present an extremely rare case of congenital cholesteatoma in identical twins.Method:Case report of congenital cholesteatoma in identical twins, and a literature review, are presented.Results:Both cases presented to the ENT out-patient clinic, but with different clinical pictures. Both were managed surgically.Conclusion:Congenital cholesteatoma presents as a whitish mass in the middle ear, with an intact tympanic membrane. It is a rare entity comprising between 3.7 and 24 per cent of total cholesteatoma cases. The key to its diagnosis is the absence of previous ear infection, ear surgery and local trauma. To our best knowledge, this paper represents the first report in the world literature of congenital cholesteatoma in identical twins.

Abstract Primary tumors of the gasserian ganglion are usually benign, and secondary tumors are malignant. We report two cases of a malignant primary tumor of the gasserian ganglion, bringing the total in the world literature to five. The presentation, etiological features, and treatment of these cases are reviewed, together with a review of the literature. Preoperative differentiation from a benign tumor is not possible with certainty. A combination of operation and radiation therapy seems to be the best treatment at present.

Sialadenoma Papilliferum

AbstractObjective:We report a rare case of sialadenoma papilliferum.Method:A case report of sialadenoma papilliferum is presented.Results:A 67-year-old woman presented with recurrent epistaxis. She was found to have an exophytic, well circumscribed mass on the nasal septum mucosa. The lesion was completely excised. A diagnosis of sialadenoma papilliferum was made based on the characteristic histological pattern. Follow up showed no evidence of recurrence. Subsequently, the patient remained well without complaint of epistaxis.Conclusion:To our knowledge, this is the first report in the world literature of sialadenoma papilliferum of the nasal cavity. This case indicates that this rare tumour can present with epistaxis, and can be resolved by means of total excision.

AbstractObjective:Carcinoma cuniculatum is a rare variant of low-grade squamous cell carcinoma. We report the second case of carcinoma cuniculatum of the larynx in the literature.Method:Case report and review of the world literature concerning carcinoma cuniculatum of the larynx and upper aerodigestive tract.Results:A histologically proven carcinoma cuniculatum of the larynx is reported in a 72-year-old man. The patient underwent a supracricoid laryngectomy with crico-hyoidopexy, and was free of disease at 70 months after surgery. We emphasise the clinical presentation, histology and therapeutic approach of this rare tumour.Conclusion:To our knowledge this is the second report in the world literature of carcinoma cuniculatum of the larynx. Carcinoma cuniculatum of the larynx must be considered as a distinct ‘clinicopathological entity’ and close cooperation between the clinician and the pathologist is essential for the correct diagnosis of these tumour as regards to the correct classification and therapy.

Hibernoma is a benign tumour, arising from vestigial remnants of brown adipose cells, which have persisted from embryonic life. Although it is a well recognized entity, it is an extremely rare tumour. Recent reports estimate 81 cases in the world literature, only seven being in the neck. To our knowledge, it has never been reported in the parotid region. We report such a case and discuss the historical background of a hibernoma, along with its pathological and clinical behaviour.

AbstractPrimary mucosal malignant melanoma (PMML) of the larynx continues to be a rare entity. To date, there are few cases reported in the world literature consisting of mainly isolated case reports and literature reviews.Traditionally believed to be radioresistant, we present a case of PMML of the right vocal fold managed with right cordectomy and adjuvant radiotherapy. The patient is well without any evidence of local recurrence or metastasis three years and four months from presentation.

Node Metastases

The clinical, light microscopic, and ultrastructural features of a carcinoid tumor occurring in the larynx of an 80-year-old man are presented and compared with 22 laryngeal carcinoids described in the world literature. These 23 tumors occurred in persons from 45 to 80 years of age (mean age was 61 years) and were three times more common in men than in women. Hoarseness was the most common presenting symptom. Sixty-one percent of the tumors were supraglottic, 26% were transglottic, 4% were glottic, 4% were subglottic, and 4% were unspecified. At least 15 (65%) of the patients are known to have developed metastases. Nine of these (60%) presnted with only regional lymph node metastases, one of which was occult. Surgery is the treatment of choice, with the extent dependent on the stage of disease. Radiation therapy appears ineffective, and chemotherapy is largely untested. The 2- and 4-year determinate survival rates were 59% and 25%, respectively.

Background. Primary breast angiosarcoma is a rare entity.Case. Initial diagnosis was a benign hemangioma at core biopsy. Wide local excision was performed, with positive margins. Pathology after surgery reported a moderately differentiated angiosarcoma. Tumor was finally treated using mastectomy and radiations. She developed a second angiosarcoma in contralateral breast, with an initial diagnosis on core biopsy of an atypical vascular lesion and was again treated using mastectomy and radiations. She developed bones and lung metastases.Conclusion. Primary breast angiosarcoma is a rare entity often difficult to diagnose on core biopsy, and a benign differential diagnosis is frequent. A highly vascular breast mass should always be considered malignant until proven otherwise. Surgical treatment seems to be the best course of action. There is a lack of data proving efficacy of adjuvant chemotherapy and radiation therapy.
