Radiological features of a rare case of pancreatic panniculitis presenting in bilateral lower extremities.

Pancreatic panniculitis is a rare cutaneous presentation in patients with pancreatic pathology. While it presents as cutaneous inflammation with painful and erythematous nodules which demonstrate ulceration, imaging features of this pathology are seldom described. The common sites of involvement are the extremities.

Lipoid proteinosis in a Chinese patient.

Lipoid proteinosis is a rare autosomal recessive deposition disorder due to loss-of-function mutations in the gene encoding extracellular matrix protein 1 on chromosome 1q21. There are limited case reports of lipoid proteinosis in the Chinese population. The authors report 1 case of lipoid proteinosis in a Chinese patient with typical clinical and histopathological manifestations.

Case of primary localized cutaneous amyloidosis with protean clinical manifestations: lichen, poikiloderma-like, dyschromic and bullous variants.

Primary localized cutaneous amyloidosis (PLCA) commonly presents as macular and lichen variants. We present a case of a 27-year-old Chinese woman with cutaneous features of the rarely reported poikiloderma-like, dyschromic and bullous forms of PLCA, and the commoner lichen variant. There were no syndromic associations or systemic involvement, and the various morphological subtypes occurred in isolation from one another.

Pruritus, pain, and small nerve fiber function in keloids: a controlled study.

Background: Keloid scars can itch and hurt, but little is known about the characteristics of these symptoms in keloids. Because itch and pain are carried by small nerve fibers, abnormal function of these fibers could be an explanation for such phenomena.

Objective: We sought to assess the characteristics of itch and pain in keloid scars, and to assess the function of small nerve fibers in keloids.
