Abstract:
Primary cutaneous mucinosis encompasses a wide range of different skin conditions with circumscribed, follicular or diffuse manifestation. For the first time, to our knowledge, we report on the occurrence of so-called "atypical" localized papular mucinosis in the axillary pits of a mother and her (identical) twin daughters presenting as asymptomatic soft minuscule papules. This unique observation allows us to define an autosomal dominant inheritance pattern with a high level of penetrance for this rare skin disease.

Cystic Fibrosis: Pathogenesis
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
