Background: Nail disorders present with a wide range of manifestations. The problems associated with nail biopsiesmake the diagnosis even more challenging. Identifying the most common features of each nail disorder can prevent unnecessary biopsies and facilitate early diagnosis.Methods: We conducted a cross-sectional study on 528 pathology reports, documented from March 2018 to March 2019 in the Razi Dermatopathology Hospital, Tehran, Iran. We extracted the demographic data and the nails’ clinical and pathologic presentations. We used Fisher’s exact test to determine the nail features’ clinicopathological correlations.Results: The mean age of the 359 included patients was 38.81 ± 18.11 years, and 50.81% were male. Benign melanonychia (12.82%), traumatic nail (11.96%), and junctional nevus (11.11%) were the most prevalent disorders. Onycholysis (P < 0.001), longitudinal ridges (P < 0.001), subungual hyperkeratosis (P = 0.003), dystrophy (P = 0.017), discoloration (P = 0.052), and pitting (P < 0.001) correlated significantly with nail psoriasis. The presence of subungual hyperkeratosis, onycholysis, and longitudinal ridges significantly increased the odds of nail lichen planus. Only 6.79% of patients with longitudinal melanonychia had malignant melanoma, while most (26.54%) correlated with benign melanonychia.Conclusions: A detailed examination can narrow the differential diagnosis and avert unnecessary biopsies. However, in high-risk cases, physicians should regularly monitor the nails’ changes and response to treatment.

Background: Basal cell carcinoma (BCC) is the most common skin cancer in whites. Objective: Determination of anatomical localization of BCC in relation to histological subtypes of this tumor. Patients and methods: This survey is a descriptive cross sectional study carried out on 189 cases of BCC patients diagnosed in Hamadan Sina hospital between 1997-1999. Results: This study showed 7 histologic subtypes of BCC. Nodular type was the most common type (55.16%) and metatypical type had the lowest frequency (3.7%). Head and neck were the most common sites of all subtypes of this tumor and nose was the most common of involvement (22.7%). Conclusion: Superficial BCC was more common on the scalp, which is due to irradiation used for the treatment of tinea capitis in the past.
