Localized primary cutaneous amyloidosis consists of three types: nodular, macular, and lichenoid amyloidosis. Lichen amyloidosis is characterized by the appearance of paroxysmally itchy lichenoid papules on the shins. Although the origin of the amyloid is controversial and can not provide any definite answer, some of amyloid substances can be derived from epidermal cells and others from degenerative collagen fibers. We suggested the origin of amyloid in our cases as epidermal keratinocyte and collagen degenerations. Because degeneration of basal keratinocyte is observed on electron microscopy and degeneration of collagen is in H&E and Masson's trichrome stain although amyloid materials are negatively stained against pankeratin antibody and collagen antibody. The skin lesion was improved after triamcinolone intralesional injections which reduce collagen synthesis. We report two cases of lichen amyloidosis which stained negatively for antikeratin antibodies and improved with triamcinolone intralesional injection.

Background: Femoral neck stress fractures (FNSFs) are rare but potentially disabling injuries if the diagnosis is missed or delayed and proper treatment is not provided. The aim of this study was to investigate and describe the characteristics and clinical course of FNSFs in South Korean male military recruits. Methods: Between May 2015 and October 2019, 16 fractures in 12 young male military recruits were reviewed. The characteristics of the fractures were ascertained by detailed analysis of the history and clinical course, as well as radiographs, bone scintigrams, and magnetic resonance images. Results: The median duration between endurance training and the development of hip pain was 5 weeks, while the median duration of pain before the patient sought medical attention was 3 weeks. Four patients (33.3%) exhibited bilateral fractures, and concomitant lesions involving the proximal tibia were found in 3 patients (25%). Fourteen of the 16 fractures (87.5%) were compression-type fractures, and surgery was performed for 7 hips. Complete union without malunion or osteonecrosis was achieved in all cases, and all cadets returned to their full activity levels in an average of 10 weeks. Conclusions We observed excellent prognosis of FNSFs. Our report highlights the importance of early reporting, detection, and treatment regarding the challenging management of FNSFs. When a military recruit reports hip pain, a FNSF should be considered; furthermore, the bilaterality of the fracture and the presence of concomitant lesions should also be investigated.

We report a case of xanthoma disseminatum in a 24 year old male paitient. Multiple yellow-brown papules developed on the flexor aurfaces, such as the neck, axillae, antecubital fossae, groin, and perianal regions. Some papules were detected arouns the eyes and uvulai. biopsy specimen revealed a dense infiltrate of histiocytes, foam cells, Touton giant cells, and other inflammatory cells. No Langerhans granules were seen in the electron microscopic analysis.
