Squamous cell carcinoma arising in long-standing necrobiosis lipoidica

JOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 2 2004
J Santos-Juanes
ABSTRACT Necrobiosis lipoidica (NL) is a disease of collagen. Squamous cell carcinomas developing in areas of chronic ulceration and scarring have been well documented in a variety of skin diseases but rarely in areas of necrobiosis lipoidica. The case history of a 76-year-old female is presented, whose squamous cell carcinoma appeared 30 years after the diagnosis of necrobiosis lipoidica. The clinical and histopathological picture is described, stressing the importance of the unusual association of the two pathologies in the prognostic. [source]


Hutchinson,Gilford progeria syndrome with severe skin calcinosis

CLINICAL & EXPERIMENTAL DERMATOLOGY, Issue 5 2007
S. Nakamura
Summary We describe a case of Hutchinson,Gilford progeria syndrome (HGPS) with long-term follow-up. A 1-month-old girl with marked sclerodermatous skin changes developed various symptoms of HGPS during follow-up. These included sclerotic skin, pigmentation, skin atrophy with translucent veins, wispy hair and alopecia, nail dystrophy and decreased sweating. Marked skin calcinosis was observed over almost the entire body, a symptom that has apparently been ignored in the literature. At 16 years old, the girl underwent surgery for a skull fracture and subdural haematoma, which was followed by chronic ulceration. Wet dressing with insulin-like growth factor was used with considerable effect. Mutation of the lamin A/C (LMNA) gene mutation, which encodes nuclear lamin A and C, has been reported to be the cause of HGPS. Our case showed the mutation G608G (GGC,GGT), which resulted in a cryptic splice site and consequently in a truncated lamin A/C protein. [source]


Reactions to Penicillamine: A Case of Cutis Laxa, Elastosis Perforans Serpiginosa and "Pseudo" Pseudoxanthoma

JOURNAL OF CUTANEOUS PATHOLOGY, Issue 1 2005
S. Frankel
This patient was a 61-year-old white female who received several years of penicillamine therapy for the treatment of cystinuria. She subsequently developed penicillamine induced cutis laxa, elastosis perforans serpiginosa, and pseudoxanthoma elasticum like skin lesions. In addition, she suffered from numerous chronic bilateral lower extremity skin ulcerations. Her past medical history was also significant for end stage renal disease requiring hemodialysis and pulmonary fibrosis. She presented to the University of Miami Wound Care Center in 1/04 for treatment of her chronic ulcerations. On physical examination, the patient had multiple large hyperpigmented plaques with central ulcerations on her lower extremities. Some of the ulcers had overlying crust and others were covered with yellow fibrinous tissue. She also had generalized thickened, lax skin with multiple folds. On her neck, thighs, back and arms were violaceous, atrophic, serpiginous plaques with peripheral crusted erosions. A biopsy taken from the patients left thigh revealed dermal elastosis and the features of pseudo-pseudoxanthoma. Two additional biopsies taken from the left thigh demonstrated elastosis perforans serpiginosa. This case highlights multiple skin manifestations of penicillamine therapy. [source]


Human cytomegalovirus-associated oral and maxillo-facial disease

CLINICAL MICROBIOLOGY AND INFECTION, Issue 6 2007
S. Doumas
Abstract Human cytomegalovirus is a ubiquitous pathogen with protean clinical manifestations. After initial infection, the virus remains in a persistent state in the host. Immunity plays a pivotal role in counteracting its virulence, albeit intermittent virus shedding occurs in immunocompetent individuals. Should deficiencies in immunity occur, e.g., as a consequence of AIDS or iatrogenic immunosuppression, then virus replication and subsequent pathogenic manifestations ensue. In the oral and maxillo-facial region, the virus causes a wide variety of diseases, mainly atypical chronic ulcerations and sialadenitis. These morbidities are rarely reported and sometimes cause significant problems for clinicians. [source]
