Background: Basal cell carcinomas (BCC) are the most prevalent among non-melanoma skin cancers (NMSC), which correspond to the most common skin cancers. BCC histopathological subtyping is a problem in therapeutic management. Therefore, we have decided to perform a histopathologic study for better classification of BCCs based on interobserver diagnostic judgment. Methods: We conducted this cross-sectional study on 100 randomly selected pathologically confirmed BCC cases of various subtypes at Razi Hospital, Tehran, Iran during 2013 and 2014. A total of four dermatopathologists independently reviewed each pathology slide to evaluate the interobserver concordance rate. Results: The overall Fleiss’ kappa statistic (kappa) for the BCC subtypes was 0.18 (P<0.001), which indicated slight agreement. We observed moderate agreement on superficial and nodular BCC (kappa: 0.0-0.4); fair agreement on infiltrative and keratotic BCC (kappa: 0.2-0.4); and slight agreement on pigmented, micronodular, and metatypical BCC (kappa: 0.0-0.2). There was moderate agreement diagnosis for the low and high risk growth pattern categories. Conclusion: Overall, we found that the dermatopathologists had inconsistent nomenclature for the BCC subtypes, however they had better agreement for the diagnosis of superficial, nodular, and infiltrative subtypes and the high risk growth pattern.

Background: Accurate clinical information provided on dermatopathology requisition forms is often very important to achieve correct diagnosis. We searched to evaluate the clinical information actually provided on the Dermatopathology requisition forms of melanocytic lesions submitted to our laboratory. Method: The provided clinical information and given microscopic diagnoses were recorded for melanocytic lesions submitted as wet tissue to our dermatopathology department. Result: Biopsy specimens were received from our dermatology clinics at our hospital that were filled in by residents of dermatology. According to ABCDE criteria, 76% of cases had none, 11.5% had one criterion, 19% had two criteria, 5.6% had 3 criteria, 1.1% had 4 criteria, and none had all 5 criteria. Asymmetry was provided in none of the requests, but border irregularity was provided in 7.6% of the time, color 10.1%, diameter 5.9%, and evolution 21.8%. No requisition forms mentioned the ‘‘ugly duckling’’ sign. Conclusion: Actually, most of the requisition forms did not provide the clinical information that is very important for the clinicopathologic correlation in the diagnosis of the pigmented lesions.

Background: Chemokines are a family of cytokines initially characterized by their capacity to induce chemotaxis, or directed leukocyte migrations. These receptors are activated by chemotactic cytokines called chemokines. Interactions between chemokines and chemokine receptors also are involved in tumorigenesis, migration and invasion of lymphoma cells.Methods: An English literature search was performed using Medline (Through Pub med; from 1995 to 2011), with limiting factors of “chemokine” and “mycosis fungoides”. Peer-reviewed articles were selected for inclusion after excluding identical papers. After reviewing all the articles, a total of 34 papers about the role of chemokines in mycosis fungoides were selected to review.Results: The potential role of specific chemokine receptors and their chemokines, including CXCR3, CCR4, CCR10, and CCR7 in the pathophysiology of mycosis fungoides, and the role of chemokines in the treatment and outcome of mycosis fungoides were discussed.Conclusion: Knowing more about the mechanisms of chemokines/ chemokine receptors interaction and use of receptor antagonists or anti-receptor antibodies as therapeutic agents could be a new modality for treatment of cutaneous T cell lymphoma.

Porokeratotic Eccrine Ostial and Dermal Duct Nevus (PEODDN) is a rare disorder of keratinization that clinically resembles comedo nevus but occurs on the palms and soles and is characterized by cornoid lamella in the histopathology. We hereunder report a young male with mildly itchy papules on the lateral surface of the left foot who was diagnosed with PEODDN upon biopsy of the lesion. We briefly reviewed the several aspects of the condition in our paper.

Mycosis fungicides (MF), on extremely rare occasions, can be associated with vesiculobullous eruptions. We describe a 74-year-old man with previous documented histopathologic diagnosis of poikilodermic type of MF who recently developed some flaccid acral bullae on erythemoatous MF plaque and normal skin. Histopathology and direct immunoflourscence studies revealed extensive lichenoid changes with intraepidermal bulla. Atypical lymphocyte infiltration was presented in dermoepidermal junction and bulla fluid and peripheral blood smear, but absent in lymph node and bone narrow tissue specimens. The plausible cause of blister formation in cutaneous lymphoma bullosa may be due to excessive epidermotropism or toxic effects of cytokines secrected by the tumoral infiltrate.
