Anastrozole-induced subacute cutaneous lupus erythematosus.

Drug-induced subacute cutaneous lupus erythematosus (DI-SCLE) has been associated with numerous drugs, but there are limited reports of its association with aromatase inhibitor anastrozole. We report the case of a patient undergoing treatment with anastrozole for breast cancer who presented with clinical, serological, and histological evidence consistent with DI-SCLE. Her condition quickly began to improve after the use of anastrozole was discontinued and hydroxychloroquine therapy was initiated. Cases such as ours as well as several others that implicate antiestrogen drugs in association with DI-SCLE seem to be contradictory to studies looking at the usefulness of treating systemic lupus erythematosus (SLE) with antiestrogen therapy. Further research on this relationship is warranted.

Silicone Granulomas, a Growing Problem?

The formation of granulomas is known to be a possible adverse effect of liquid silicone administration, used for soft tissue augmentation. Its plumping effects provide enhancement of certain body parts, such as the lips, hips, and buttocks. The desire for enhancement, perhaps influenced by popular culture and an unrealistic standard of beauty, leads individuals to seek silicone injections. There is a growing population of women and men receiving injections by unlicensed, unskilled "practitioners" not related to the healthcare profession. Complications under such circumstances are not uncommon, particularly the emergence of silicone granulomas, and the authors' medical center has seen an increase in such cases. In this case report, the authors illustrate a young patient with significant complications from her silicone injections, review current therapies for silicone granulomas, and discuss this growing medical problem.

Pemphigus foliaceus exacerbated by radiation, in association with myasthenia gravis.

Pemphigus foliaceus (PF) is a sporadic autoimmune blistering disease of unknown etiology. The production of immunoglobulin G4 antibodies against desmoglein-1 is responsible for the clinical manifestation of PF. We present a case of a woman with a recent diagnosis of myasthenia gravis (MG), who was also recently treated with radiation therapy for breast cancer. The clinical exam, supported by biopsy and direct immunofluorescence, were consistent with PF. We present this case to increase the awareness of the potential exacerbation or induction of PF with radiation, and of the association of PF and myasthenia gravis. Only five prior cases of radiation-exacerbated or radiation-induced PF have been reported in the literature to date. Furthermore, the co-existence of the autoimmune entities of myasthenia gravis and PF has been reported in the literature in only 9 cases and was also noted in this patient.

Computer-assisted diagnosis of melanoma.

The computer-assisted diagnosis of melanoma is an exciting area of research where imaging techniques are combined with diagnostic algorithms in an attempt to improve detection and outcomes for patients with skin lesions suspicious for malignancy. Once an image has been acquired, it undergoes a processing pathway which includes preprocessing, enhancement, segmentation, feature extraction, feature selection, change detection, and ultimately classification. Practicality for everyday clinical use remains a vital question. A successful model must obtain results that are on par or outperform experienced dermatologists, keep costs at a minimum, be user-friendly, and be time efficient with high sensitivity and specificity.

Necrolytic migratory erythema associated with fatty liver disease and the psuedoglucagonoma syndrome.

We report a 48-year-old woman with a past medical history of psoriasis, nonalcoholic steatohepatitis (NASH), and type II diabetes mellitus, who presented to the emergency department with a 1 week history of erosive annular plaques with associated atrophy and telangiectasias on her legs bilaterally, thighs and buttock, histopathologically consistent with necrolytic migratory erythema. Although classically associated with a pancreatic glucagonoma, this patient experienced this figurate erythema in the setting of fatty liver disease with no glucagonoma. The rarity of pseudoglucagonoma syndrome, or necrolytic migratory erythema occurring in the absence of a glucagonoma, warranted the discussion of this case.

Leuprolide acetate-induced generalized papular eruption.

Leuprolide acetate, a gonadotropin-releasing hormone agonist, is used in the treatment of prostate cancer. We report a unique case of a disseminated papular rash following leuprolide acetate injections in a 65-year-old man that shares clinical and histopathological features of papuloerythroderma of Ofuji. Leuprolide-induced papuloerythroderma, as well as a limited number of other disseminated cutaneous eruptions caused by this drug, is extremely rare, with only one case previously reported. Our case calls attention to this uncommon side effect in a commonly used hormonal therapy.

Endometriosis in the rectus abdominis muscle: case report and literature review.

Endometriosis is characterized by the presence of histologically normal endometrial tissue outside the uterine cavity. Endometriosis occurs most commonly within the pelvis. Extrapelvic endometriosis is less common, but can involve nearly every organ in the body. We present a patient in whom endometriosis was discovered in the rectus abdominis muscle and discuss the imaging findings and histopathology.

Tattoo removal.

Tattoos have been a part of costume, expression, and identification in various cultures for centuries. Although tattoos have become more popular in western culture, many people regret their tattoos in later years. In this situation, it is important to be aware of the mechanisms of tattoo removal methods available, as well as their potential short- and long-term effects. Among the myriad of options available, laser tattoo removal is the current treatment of choice, given its safety and efficacy.

The relationship of plasma glucose and HbA1c Levels among emergency department patients with no prior history of diabetes mellitus.

OBJECTIVES: Patients without a history of diabetes mellitus may be incidentally found to be hyperglycemic in the emergency department (ED). If the hyperglycemia is due to undiagnosed diabetes, then an opportunity for detection exists. Hemoglobin A1c (HbA1c) provides a weighted average of blood glucose levels over the past several months; high HbA1c levels could indicate diabetes. The objective of this study was to determine whether hyperglycemia in ED patients without a history of diabetes was associated with higher HbA1c levels. METHODS: This was a prospective nonconsecutive case series of adults aged 18 years or older presenting to the ED with acute illness for whom a plasma glucose sample was drawn for clinical management. A history of diabetes/hyperglycemia or current symptoms of diabetes excluded patients. HbA1c levels were analyzed for a glucose cutoff of 110 mg/dL; the data were further analyzed using additional glucose cutoffs. Based on the Third National Health and Nutrition Examination Survey outpatient screening data, an HbA1c level > or =6.2% was considered elevated (sensitivity of 63% and specificity of 97% for identifying diabetes). RESULTS: There were 541 patients enrolled; the glucose level correlated with the HbA1c level (r = 0.60, p < 0.001). Among the 331 patients with a glucose level > or =110 mg/dL, 22.4% had an elevated HbA(1c) level; among the 210 patients with a glucose level < 110 mg/dL, 7.6% had an elevated HbA1c level. There were few patients (n = 13) with a glucose level > or =200 mg/dL, but most (85%) had an elevated HbA1c level. Among the 140 patients with a mildly elevated glucose level (110-125 mg/dL), 16.4% had an elevated HbA(1c) level. CONCLUSIONS: Elevated HbA1c levels are found in ED patients with elevated random plasma glucose values. ED patients with hyperglycemia may warrant referral for diabetes testing.
