Size of metastatic lymph nodes.

We present a case and review of the literature of well-differentiated sigmoid adenocarcinoma with numerous metastases into pericolic lymph nodes. All positive lymph nodes were small. The authors concluded that there is no clear correlation between nodal size and the likelihood of metastasis in the lymph node, and the status of small lymph nodes must receive special attention by clinicians and pathologists.

The reproducibility of histological parameters employed in the novel binary grading systems of endometrial cancer.

Objective: To compare the interobserver reproducibility and prognostic value of the FIGO grading system with the histological parameters employed in the various recently proposed binary grading systems of endometrial cancer.

Methods: Seventy two consecutive stage I endometrioid endometrial carcinomas from hysterectomy specimens were independently graded by two pathologists. Clinical data and outcome were obtained from the patients' records.

The outcome of patients with stage I endometrial cancer involving the lower uterine segment.

The objective of this study was to evaluate whether lower uterine segment involvement (LUSI) correlates with recurrence and survival in women with stage I endometrial adenocarcinoma and whether it is associated with poor prognostic histopathologic features. Three hundred seventy-five consecutive patients with endometrial carcinoma stage I compromised the study population. The patients were divided into two groups according to the presence of LUSI with endometrial carcinoma.

Malignant phyllodes tumor with heterologous liposarcomatous differentiation and tubular adenoma-like epithelial component.

Phyllodes tumor of the breast is a biphasic fibroepithelial neoplasm. A 30-year-old woman presented with a 1-year history of a palpable, asymptomatic right breast mass without axillary lymphadenopathy and family history of breast carcinoma. Malignant phyllodes tumor was diagnosed.

Triple-barreled type of appendiceal triplication.

Appendiceal anomalies are extremely rare malformations. The authors present a type of appendiceal triplication not previously described in an adult patient with review of the literature. Microscopic examination of postappendectomy specimen revealed acute perforative appendicitis associated with formation of three separate appendiceal lumina.
