Diagnosis of large granular lymphocytic leukemia in a patient previously treated for acute myeloblastic leukemia

Large granular lymphocytic (LGL) leukemia is a lymphoproliferative disease characterized by the clonal expansion of cytotoxic T or natural killer cells. We report on a patient diagnosed with T-cell LGL leukemia two years after the achievement of hematologic remission for acute myeloblastic leukemia.

The role of p53, Bcl-2 and Ki-67 in premalignant cervical lesions and cervical cancer

PURPOSE

The aim of this study was to determine the role of p53, Bcl-2 and Ki-67 expression in the carcinogenesis of cervical carcinoma and aggressiveness of cervical intraepithelial neoplasia (CIN).

METHODS

The pathology specimens of 63 patients with a diagnosis of normal squamous epithelium (22 cases), CIN I (14), CIN II (5), CIN III (8) and squamous cell carcinoma (14) were evaluated immunohistochemically for the expression of p53, Bcl-2 and Ki-67 in paraffin sections.

RESULTS

The expression of p53 and Ki-67 increased proportionally to the grade of CIN and cervical cancer, but only the increase of p53 expression was statistically significant (p = 0.002). There was no significant correlation between Bcl-2 expression and premalignant and malignant cervical lesions.

CONCLUSION

p53 expression may have a role in the carcinogenesis of squamous cell cervical carcinoma whereas Bcl-2 expression has no role. Ki-67 expression can not be used in determining the aggressiveness of CIN lesions.

Lipomatosis of the bladder presenting as bladder cancer

A case of bladder lipomatosis in an 81-year-old man is presented. The preoperative diagnosis was bladder tumor. A transurethral resection of the bladder was performed and a pathological examination revealed lipomatosis of the bladder. This entity is extremely rare and, to our knowledge, this is the second case reported in the English published works.
