Capsule Endoscopy in the Diagnosis, Disease Mapping, and Monitoring of Treatment Response in Gastrointestinal Whipple's Disease.

Whipple's disease is a rare systemic infection causing malabsorption. Affected patients often undergo extensive investigation until final diagnosis with periodic acid-Schiff-positive histology. We present the case of a 73-year-old man diagnosed with Whipple's disease after a prolonged history, with a focus on capsule endoscopy (CE) in both mapping the extent of the pathology and follow-up. We demonstrate pre-treatment and post-treatment CE images, allowing visualization of resolved small bowel pathology, and demonstrate histological resolution. The early use of CE in the investigation of Whipple's disease may expedite diagnosis in patients with more distal bowel pathology and help assess disease severity.

Conjunctival Melanoma with Ipsilateral, Non-Contiguous Eyelid Involvement: A Case Report and Comprehensive Review of the Literature.

While the majority of cases of conjunctival melanoma (CM) involve the bulbar conjunctiva, concurrent pigmentation of the ipsilateral eyelid can be seen in up to 15% of cases. Although extension of conjunctival melanoma into the eyelid (AJCC cT3b) occurs in 1% of cases, non-contiguous lesions are very rare with only 5 clearly documented reports in the English literature. Several pathophysiological mechanisms have been proposed, including separate primary melanomas, patchy involvement from primary acquired melanosis (which may be sine pigmento) and exfoliation of malignant tumour cells into the tear film. Herein we present a case of eyelid melanoma arising in a patient previously treated for CM at a non-contiguous site and provide a comprehensive review of the relevant literature.

Primary Gallbladder Lymphoma in a Male Patient with No Risk Factors Detected Incidentally by CT Colonography.

Primary gallbladder lymphoma, although rare, usually presents in females with symptoms mimicking cholecystitis. We present a rare case of primary gallbladder in an 81-year-old male with no risk factors whose only symptom was weight loss. Routine blood tests including liver function tests were unremarkable. A CT colonography was carried out to exclude colonic malignancy. Unilateral gallbladder wall thickening and lymphadenopathy were incidentally detected and confirmed by ultrasound and a decision for the patient to undergo laparoscopic cholecystectomy and intraoperative cholangiogram was made. Histology confirmed extranodal marginal zone lymphoma with follow-up staging and biopsy of the bone marrow not demonstrating spread. Cholecystectomy was therefore deemed curative and no adjuvant therapy was necessary. Thickening of the gallbladder wall on any imaging with or without symptoms should not be ignored or assumed to be cholecystitis, even in males with no risk factors. In these patients urgent cholecystectomy with intraoperative cholangiogram is indicated with histology and haematology follow-up.

Nuclear grade plus proliferation grading system for invasive ductal carcinoma of the breast: validation in a tertiary referral hospital cohort.

OBJECTIVES: For patients with invasive breast cancer, management decisions are informed by tumor grade according to the Nottingham Grading System (NGS), either on its own or as part of the Nottingham Prognostic Index (NPI). A system retaining the nuclear grade element but substituting the two subjective components, mitosis count and tubule formation, of the NGS with a proliferation index based on Ki-67 (MIB-1) has been proposed (nuclear grade plus proliferation [N+P] grading). METHODS: We validated the prognostic value of this grading system on a population of 322 women. RESULTS: N+P grading resulted in more grade I tumors (47.9% vs 4.5%) and fewer grade II (32% vs 51.5%) and grade III (20.1% vs 44%) tumors compared with NGS. The NPI calculated based on N+P grade had a similar association with survival (P < .001; odds ratio, 1.729) as the NPI calculated on the basis of the NGS grade (P < .001; odds ratio, 1.668). CONCLUSIONS: The N+P system seems equivalent to the NGS system.

An unexpected finding of a rare intrascrotal lesion: the sertoliform cystadenoma of the rete testis.

A 19-year-old man presented with a right testicular swelling. Testicular ultrasound demonstrated areas suspicious for malignancy and so it was decided to proceed for a right radical inguinal orchiectomy. Initial histological examination revealed a multiloculated cystic lesion at the area of the rete testis yet normal testicular parenchyma elsewhere. Specialist histological opinion was sought from the regional teratoma multi-disciplinary team which confirmed the diagnosis of a sertoliform cystadenoma, an extremely rare benign testicular neoplasm. The recognition of the benign nature of the mass enabled complete reassurance to be offered to the patient and avoided further oncological treatment.
