Mixoglobulosis del apéndice: una causa rara de dolor pélvico

Abstract

Myxoglobulosis, also known as caviar appendix, is an unusual and rare variant of appendix mucocoele. I report a case of a 29-year-old woman who presented with a 6 day history of pelvic pain after pelvic ultrasound revealed an enlarged appendix. Macroscopically, the appendix had a proximal occlusive membrane and the lumen was distended by pearl-like cream white spheroids measuring 2–7 mm in diameter. Sectioning of the appendix revealed the presence in the dilated appendiceal lumen of numerous whitish opaque globules ranging in size from 0.2 to 0.7 cm in diameter. On microscopic examination, the globules consisted of faintly eosinophilic laminations of mucin surrounding an amorphous granular core. The mucin was identified by positivity with histochemical mucin stains. After thorough microscopic examination of the appendix, our case was diagnosed as myxoglobulosis .The features of myxoglobulosis will be discussed as well as a brief review of the relevant literature.
