Background:Seborrheic keratosis (SK) is the most common benign epidermal tumor of the skin. Even though SK has been well characterized clinically, dermoscopically, and histopathologically, data regarding clinical dermoscopic and histopathological correlation of different types of SK are inadequate.Aim:We carried out this study to establish any correlation between the clinical, dermoscopic, and histopathological appearance of SK and its variants.Methods:This was a descriptive study. Patients with SK were evaluated with respect to age, sex, family history of similar lesions, site of lesions, and symptoms associated with the lesions. Dermoscopy was performed in all cases. Biopsies were taken from the lesions and assessed for histopathology.Results:The most common age group affected by SK was 31–50 years (42%). A female preponderance of 76% was seen. Majority of our patients had a positive family history (62%), though Sun exposure was not seen to be a major factor. The most common clinical variant was common SK (CSK) (46%). The most common dermoscopic findings seen in CSK were comedo-like (CL) openings, fissures and ridges (FR), and milia-like (ML) cysts. Dermatosis papulosa nigra and pedunculated SK had characteristic FR and CL openings on dermoscopy. Stucco keratoses showed network-like (NL) structures and sharp demarcation. CL opening on dermoscopy corresponded to papillomatosis and pigmentation, ML cysts corresponded to horn cysts, FR corresponded to papillomatosis, and NL structures corresponded to an increase in basal layer pigmentation.Conclusions:This study emphasizes the use of dermoscopy in improving the diagnostic accuracy of SK. The correlation between the various histological and dermoscopic features is described.

tissue necrosis, mucocutaneous ulcers, and paronychia. 1,5 Metastatic lesions are particularly concerning as they result from bacteremia. In our patient, nodular skin lesions were confined to her lips, which could represent metastatic and/or local infiltration of the organisms.Because of extensive antibiotic resistance, highdose TMP-SMX is the recommended treatment for S maltophilia; however, this can worsen neutropenia in the immunocompromised patient. 2 Combining TMP-SMX with an extended-spectrum cephalosporin or ticarcillin-clavulanate is another proposed therapeutic option. 2 We describe a patient with recurrent episodes of S maltophilia bacteremia and prominent lip nodules despite initial antimicrobial therapy. Her cutaneous findings and bacteremia likely represent either metastatic infiltration from an infected intravascular catheter or mucous membrane colonization followed by subsequent locally invasive infection and bacteremia. Although S maltophilia can be a colonizer, bacteremia signifies infection and should prompt treatment with TMP-SMX and removal of infected intravascular devices. Clinicians should be aware of S maltophilia and consider this pathogen in the differential diagnosis of lip swelling in immunocompromised patients.

Spectrum of seborrheic keratoses in south Indians: A clinical and dermoscopic study

Abstract: The most common clinical variant of SK was CSK, followed by DPN, PSK, Flat SK, and stucco keratoses. Dermoscopic findings were consistent with those described in the literature.
