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.

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.

Article Synopsis
  • Primary gallbladder lymphoma is rare and typically affects females, presenting with symptoms similar to cholecystitis; this case involves an 81-year-old male with weight loss as the only symptom.* ! -
  • Routine blood tests were normal, but imaging revealed gallbladder wall thickening and lymphadenopathy, leading to laparoscopic cholecystectomy and cholangiogram.* ! -
  • Histological analysis confirmed extranodal marginal zone lymphoma, and since there was no spread, the surgery was curative and no additional treatment was needed; this emphasizes the importance of further investigation for gallbladder wall thickening.* !

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.

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.
