Acute3
The diagnosis is often made based on clinical signs and symptoms of acute appendicitis or coincidentally via imaging methods when it is asymptomatic. (acquaintpublications.com)

Epithelial1
Unlike the invasive carcinomas, borderline ovarian tumors are characterized by cytoplasmic and nuclear atypia, (element of differential diagnosis with benign tumors), absence of stromal invasion, (element of differential diagnosis with malignant tumors), unusual degree of proliferation of the epithelial cells with cellular stratification including remarkable architectural atypia and the formation of papillary protuberances.

Histology2
Peritoneal implants are very uncommon (15%), and when they occur, a mixed histology as well as the presence of pseudomyxoma peritonei must be ruled out. (wikipedia.org)
Incidental appendectomy in the absence of contraindications is an option because although the gross appearance of the appendix may be unremarkable, histology may demonstrate appendicitis or other pathologies such as endometriosis, neoplasia, obstruction by appendicoliths, or parasites. (webop.com)

If ultrasonography demonstrates a vermiform appendix/residual appendix 6-8 weeks later, interval appendectomy should be performed. (webop.com)
Diagnosis4
The symptoms of PMP are often non-specific and vague, causing difficulties in diagnosis. (amsj.org)
The clinical implications of this are that PMP is not commonly considered a differential diagnosis in patients with these symptoms, which may then delay the diagnosis being made. (amsj.org)
