Multiple fire ant stings: report of 3 cases and review of the literature.

Imported fire ant sting reactions are becoming an increasing problem in the United States. It is important for clinicians to be familiar with their possible cutaneous and noncutaneous presentations. We present 3 cases with multiple fire ant stings, followed by a review of the literature.

Acute periorbital mucinosis in discoid lupus erythematosus.

Periorbital edema associated with lupus erythematosus is not frequently reported. To our knowledge, periorbital edema from increased dermal mucin has not been reported with any form of lupus. We present a patient with discoid lupus exhibiting periorbital edema from massive mucinosis.

Tretinoin-induced sticky skin: a case report and review of the literature.

Sticky skin has been reported relatively infrequently in the literature in association with etretinate and doxorubicin/ketoconazole administration. It has a poorly understood pathogenesis, and the associated histologic changes have not been described. We report a case of a patient who experienced sticky skin in areas treated with tretinoin. These reverted to normal after cessation of treatment. In comparison to a biopsy taken while the skin was not sticky, the histologic findings included a thickened, compact stratum corneum and granulosum. The basal epithelial cells showed proliferation with slight crowding and a tall, columnar shape. To our knowledge, this is the first report of sticky skin occurring in response to topical retinoid application. We suggest that the histologic changes observed could represent a modified keratin maturation profile.

Treatment of tinea nigra with terbinafine.

We present the first reported cases of tinea nigra treated with terbinafine. Two cases responded to treatment with topical terbinafine; one case failed to respond to treatment with systemic terbinafine.

Hypersensitivity reactions to parenteral vitamin K.

Cutaneous hypersensitivity reactions to vitamin K are rare. They occur almost exclusively with fat-soluble vitamin K (K1). The lesion is most commonly a pruritic, indurated plaque at the site where the vitamin was injected. Most plaques resolve within 4 to 8 week without sequelae, but some progress to produce scar-like changes that may last for years.

Frequency of pre-existing actinic keratosis in cutaneous squamous cell carcinoma.

BACKGROUND: Controversy over the rate of malignant transformation of actinic keratosis (AK) into cutaneous squamous cell carcinoma (SCC) has generated considerable debate regarding the importance of treating all such precancers to preclude their transofrmation. Current changes in US healthcare policy will deny many individuals access to certain simple and effective treatment modalities for precancerous lesions. OBJECTIVE: Our purpose was to determine whether there is a significant association between the presence of cutaneous SCC and pre-existing AK. METHODS: One hundred and sixty five consecutive cases of cutaneous SCC, retrieved from the files of a university-affiliated dermatopathology laboratory serving north-central Florida, were selected for review by a single dermatopathologist (D.M.). Hematoxylin and eosin stained skin tissue slides were examined under light microscopy for the presence of AK in close proximity to, or giving rise to, cutaneous SCC. RESULTS: Of the 165 cutaneous SCC cases reviewed, 82.4% (136 out of 165) were found to have concomitant AK giving rise to and/or in close proximity to SCC. Of the 136 AK-positive SCC cases, 26.7% (44) were identified as superficial SCC arising within an AK (AKSSCC) and 55.7% (92) had AK in close proximity to SCC (AK + SCC). Close proximity is defined to include AK changes located directly adjacent to (on the shoulder of) SCC, to a maximum distance of 8 mm away. CONCLUSIONS: The 82.4% prevalence of concomitant AK and cutaneous SCC in our biopsy population suggests a strong correlation between these two lesions. The fact that 26.7% of these lesions had SCC arising from AK highlights the importance of early recognition and effective treatment for AK.

Congenital cutaneous candidiasis associated with respiratory distress and elevation of liver function tests: a case report and review of the literature.

We describe congenital cutaneous candidiasis (CCC) in a term newborn. The mother had candidal vaginitis 1 week before delivery. At birth, the infant had a generalized, intensely erythematous, papulovesicular eruption, respiratory distress and elevation of liver function tests. The child responded well to intravenous amphotericin B plus topical and oral nystatin. There have been 13 previously reported cases of CCC in infants weighing more than 1500 gm who had evidence of systemic infection. Two deaths were attributed to candidal pneumonia and sepsis. The majority of infants with CCC have infection localized to the skin, but if there is any evidence of respiratory distress or signs of sepsis the possibility of systemic candidiasis and the need for parenteral antifungal therapy must be considered.

Erythrokeratoderma variabilis: case report and review of the literature.

A 5-month-old boy with erythrokeratoderma variabilis is presented. The parents noted that the asymptomatic erythematous plaques changed over the course of hours to days. Topical therapy with retinoic acid proved ineffective. A brief review of the literature is presented.
