Androgenetic alopecia is often treated by follicular unit transplantation, a technique that involves minimal risk of hair loss because of the more resistant nature of the donor area. Lichen planopilaris is a cicatricial alopecia that causes permanent destruction of hair follicles. We report two cases of post-transplantation lesions compatible with lichen planopilaris in both recipient and donor...

Sox9 is a master regulatory gene involved in developmental processes, stem cells maintenance and tumorigenesis. This gene is expressed in healthy skin but even in several skin neoplasms, where its expression patterns often resembles those of the developing hair follicle. In this study, samples from eleven different types of canine skin neoplasms (squamous papilloma, squamous cell carcinoma, inf...

tion, and the lipidized DF, with a homogeneous yellowish area.3,6 Although initially considered rare, sebaceous structures are identified in more than 15% of DFs,4,5,7 even in multiple forms.8 This finding is typical in lesions localized in the anatomical area of the shoulder (shoulder, proximal region of the arm, upper back and deltoid region), being observed in more than 40% of these cases, p...

173 I read with interest the article entitled “Multiple Large Cysts Arising from Nevus Comedonicus” by Jeong et al. [1]. I believe it is very difficult to cure nevus comedonicus (NC), as I have experienced performing repeated surgery for NC. The authors described a magnetic resonance imaging (MRI) scan that detected 5 cystic masses, but there were three resected masses and sets of physical find...

Gallbladder polyps are growing masses inside the wall of the gallbladder. In the majority of patients, the diagnosis represents an incidental finding of a routine abdominal u l t rasonography, or fo l lowing cholecystectomy for gallstones. The overwhelming majority of these lesions are non-neoplastic therefore called as pseudo-tumor. The widespread use of ultrasonography has made the diagnosis ...

The expressions of cytokeratin 8 and 18 (CK8 and CK18) in the normal canine skin (2 cases) and cutaneous adnexal tumors (127 cases) were investigated immunohistochemically. In the normal skin, co-expression of CK8/18 was found in the glandular epithelium of apocrine sweat glands, and single CK8-immunoreactivity was detected occasionally in the external root sheath at the isthmus and suprabulbar...
