The nasal manifestations of sarcoidosis: a review and report of eight cases.

We report eight patients presenting to the Department of Otorhinolaryngology between 1990 and 1998 in whom a diagnosis of sarcoidosis was made. The most common presenting symptom was that of nasal obstruction and crusting and the most common site of involvement was the septum and inferior turbinate. These patients differ from the majority of patients who present with the other manifestations of sarcoidosis in that they are older. Where mucosal changes are present within the nose, biopsy gives a high diagnostic yield. The aim of treatment is to gain symptomatic control with the lowest dose of steroids. The majority of patient's nasal symptoms were managed with local measures and topical steroids. Nasal disease tends to follow a prolonged but benign course. Few had other organ involvement. While nasal sarcoidosis remains a rare cause of nasal obstruction, biopsy of abnormal nasal mucosa along with further investigations as dictated by history, examination and histological findings is important if delay in diagnosis is to be avoided.

Transtubal spread of endometrial carcinoma: correlation of intra-luminal tumour cells with tumour grade, peritoneal fluid cytology, and extra-uterine metastasis.

AIMS: To assess the significance of intra-luminal tumour cells (ILTC) within the fallopian tubes of patients with endometrial carcinoma, with emphasis on high grade histological subtypes. METHODS: Complete histological examination of fallopian tube tissue was performed in 36 low grade endometrioid adenocarcinomas and in a consecutive series of 226 high grade endometrial malignancies including 92 serous carcinomas, 64 grade 3 endometrioid carcinomas, 26 carcinosarcomas, 25 undifferentiated/dedifferentiated carcinomas, and 19 clear cell carcinomas. The presence of ILTC was correlated with peritoneal fluid cytology, histologically confirmed peritoneal tumour spread, and lymph node metastases. RESULTS: ILTC were identified in 26% and 3% of high and low grade carcinomas, respectively. The presence of ILTC correlated strongly with positive peritoneal fluid cytology and with peritoneal metastasis in high grade tumours (both p < 0.001), and there was also a correlation with lymph node metastasis (p = 0.049). ILTC were more common in serous and undifferentiated carcinomas (>30%) but the differences between the high grade tumour subtypes were not statistically significant. CONCLUSIONS: These findings suggest that ILTC associated with high grade endometrial cancers have the capacity to implant and invade the peritoneal cavity. Positive cytology in such cases may be more significant than in low grade tumours. Complete tubal examination may provide additional prognostic information in high grade endometrial carcinoma.

Isolated unilateral hypoglossal nerve paralysis caused by an atlanto-occipital joint synovial cyst.

An isolated unilateral hypoglossal nerve lesion is an uncommon cranial nerve palsy. We report a case of isolated hypoglossal nerve paralysis caused by an intra-dural synovial cyst. To our knowledge, this is the first reported case of a twelfth nerve paralysis caused by a synovial cyst. The anatomy of the hypoglossal nerve, its blood supply and the relationship of the nerve to the atlanto-occipital joint are reviewed, along with the common causes of isolated hypoglossal nerve paralysis.

Richter's hernia of the splenic flexure: computed tomography appearances.

A case of a clinically occult Richter's hernia of the splenic flexure, through an anterior abdominal wall defect, is described. In view of the initial absence of bowel obstruction with a partial or Richter's hernia, and in the absence of physical findings, the importance of computed tomography (CT) in demonstrating abdominal wall lesions is highlighted.
