ABSTRACT
Pachyonychia congenita (PC) is a rare autosomal dominant genetic skin disorder due to a mutation in any one of the five keratin genes, KRT6A, KRT6B, KRT6C, KRT16, or KRT17. The main features are palmoplantar keratoderma, plantar pain, and nail dystrophy. Cysts of various types, follicular hyperkeratosis, oral leukokeratosis, hyperhidrosis, and natal teeth may also be present. Four unrelated Indian families presented with a clinical diagnosis of PC. This was confirmed by genetic testing; mutations in KRT17 were identified in all affected individuals.
ABSTRACT
Angioma serpiginosum is a cutaneous vascular nevoid disorder that presents as red, nonblanchable and grouped macules distributed in a serpiginous pattern and resembles purpura. It usually begins in childhood and commonly affects the lower limbs and the buttocks. Late onset of the lesions is unusual. We report a 46-year-old female who presented with progressively extending lesions on her breast since preceding four years. She also had a cherry angioma overlying the lesions, an observation hitherto not reported so far.
ABSTRACT
Two infants developed hyperpigmented curvilinear patches on the posterior heel after wearing heel-length socks. Both of the patient's lesions improved after discontinuing the use of the heel-length socks. Hyperpigmented patches called sock-line or mitten-line hyperpigmentation have been reported at sites of tight elastic bands from socks or mittens in infants on the calves and wrists. Recognizing this clinical entity is important to differentiate it from other causes of linear lesions such as child abuse or amniotic band syndrome.

Eusol (an abbreviation for Edinburgh University solution), consisting of aqueous boric acid and calcium hypochlorite, is widely used in the management of open wounds left to heal by secondary intention (1).
