Paget’s disease of the breast is a rare type of cancer of the nipple–areola complex and that is often associated with an underlying in situ or invasive carcinoma. It is often misdiagnosed as eczema of breast and treatment is delayed. Here we present a case where a 30 year old female presented with itching ulceration and destruction of her left nipple. She was treated initially by local physicians by applying local ointments but as her condition did not improve she was admitted to department of surgery Shaheed Suhrawardy Medical College hospital where she was diagnosed as Paget’s disease with infiltrating ductal cell carcinoma. She underwent modified radical mastectomy with axillary clearance and referred to oncology department for further management. J Shaheed Suhrawardy Med Coll, June 2019, Vol.11(1); 81-83

Long Term Follow Up

Background: PReferentially expressed Antigen in MElanoma (PRAME) immunohistochemistry is increasingly used as diagnostic adjunct in the evaluation of melanocytic tumors. The expression and prognostic significance of PRAME in melanomas ≤1.0 mm and its diagnostic utility in the distinction from severely dysplastic compound nevi (SDN) have not been studied. Methods: We investigated and compared the immunohistochemical PRAME expression in 70 matched thin metastasizing and non-metastasizing melanomas and 45 nevi from patients with long-term follow-up (35 SDN and 10 unequivocally benign compound nevi). Results: Diffuse PRAME staining in >75% of lesional epidermal and dermal melanocytes identified 58.6% of thin melanomas but did not distinguish metastasizing from non-metastasizing melanomas (p = 0.81). A superficial atypical melanocytic proliferation of uncertain significance, in which the final diagnostic interpretation favored a SDN was the only nevus with diffuse PRAME expression (1/45). Melanomas and SDN with PRAME immunoreactivity exhibited different staining patterns. Most melanomas (67.6%) showed uniform PRAME expression in the in situ and invasive component, whereas most SDN (81.0%) showed a decreasing gradient with depth. Conclusion: Diffuse intraepidermal and dermal PRAME staining is highly specific for melanomas in the distinction from SDN. PRAME expression is not a prognostic biomarker in melanomas ≤1.0 mm.

Numerous cells with very large and irregular nuclei (“monster” cells) have not hitherto been reported in desmoplastic melanoma (DM). Their prognostic significance in melanomas is a matter of debate, although some authors have associated them with more aggressive tumor behavior. We report a mixed DM on the scalp of an 88-year-old woman imitating an atypical fibroxanthoma. Tumor cells stained positive for SOX10, S100, and cyclin D1; BRAF mutation status was negative, and fluorescence in situ hybridization analysis showed copy number gains in 11q13 (cyclin D1) and 6p25 (RREB1), and loss in 6q23 (MYB). Cyclin D1 amplification is associated with poor prognosis in melanoma.

Background. We described a patient with chronic lymphocytic leukemia (CLL) and lung cancer and unusual chromosomal aberrations. Case report. At the same time with the diagnosis of B-cell CLL, squamocellular lung carcinoma diagnosis was established. Using interphase fluoresecence in situ hybridization technique (FISH) we detected monosomy 12 and deletion of 13q34 occured in the same clone. One month after the beginning of examination the patient died unexpectedly during sleep immediately before we applied a specific treatment for CLL or lung carcinoma. Conclusion. Simultaneous occurrence of monosomy 12 and deletion of 13q34 in a patient with B-cell CLL has been described only once before, but as a part of a complex karyotype. The prognostic significance of these abnormalities remains uncertain.
