Pseudofolliculitis barbae associated with an unusual hair whorl.
Descriptions of hair direction in the literature have emphasized unusual patterns of the scalp and associated developmental brain defects. We present the case of a white patient with unilateral pseudofolliculitis barbae associated with a hair whorl in the inframandibular region. To our knowledge, this is the first reported case of pseudofolliculitis barbae associated with a hair whorl.
Xanthomatized atypical T cells in a patient with mycosis fungoides and hyperlipidemia.
BACKGROUND: Lipoprotein-T-cell interactions are being reported with increasing frequency, and there is evidence that lipoproteins play a role in immunoregulation. We describe a patient with mycosis fungoides and hyperlipidemia who developed xanthomatization in one preexisting plaque. The case is unique in that some of the lipidized cells were atypical T cells. In previously reported cases of mycosis fungoides with dystrophic xanthomatosis, the lipid-containing cells have been identified only as histiocytes. OBSERVATIONS: Immunopathologic features, electron microscopy, and lipid stains of the xanthomatized plaque demonstrated that some of the lipid-laden cells were atypical T cells. CONCLUSIONS: In mycosis fungoides, malignant T cells may be intimately involved in processing of tissue lipids. We suggest that low-density lipoprotein receptors on activated T cells facilitated the cytoplasmic lipidization in this case.
Widespread Candida folliculitis in a nontoxic patient.
We present a case of widespread Candida folliculitis in a nontoxic, immunocompetent woman. Predisposing factors included obesity and use of systemic antibiotics and topical steroids. Diagnosis was made through potassium hydroxide and Gram's stain examination of the pustular contents. The patient was treated with oral ketoconazole and topical econazole, with resolution of the eruption in six weeks. We suggest that temperature played a role in the follicular location of the lesions.
Pseudomonas toe web infections.
We present the case of a patient with a presumed tinea pedis infection who was referred to us after being treated with oral griseofulvin for two weeks with no improvement. We used a simple Wood's light examination and culture to establish the diagnosis of Pseudomonas toe web infection and achieved rapid resolution with oral ciprofloxacin treatment and local application of Castellani's paint.
Ichthyosiform scaling secondary to megavoltage radiotherapy.
Acquired ichthyosis is a rare dermatosis associated with a number of malignancies. Side effects seen on the skin secondary to megavoltage radiotherapy are uncommon but may include fine dry desquamation and tanning. We present a case of ichthyosiform scaling limited to the radiation fields in a patient treated for brain metastases of a primary small cell lung carcinoma. The reader is reminded that side effects of megavoltage treatment do occur on the skin. A brief review of these effects is included.

Measurement of impotence by laser Doppler flowmetry and conventional methodology.
The problem of vasculogenic impotence was evaluated by laser Doppler flowmetry with the LD5000 capillary perfusion monitor to determine cutaneous penile blood flow in 25 men defined previously as impotent by Doppler ultrasound with penile brachial ratios of 0.63 +/- 0.14. Erotic visual stimulation for 1, 2 and 4 minutes did not statistically change the cutaneous flow as measured by laser Doppler flowmetry from its baseline of 20 mv. The dynamics of skin microcirculation in the penis may reflect changes in the deeper vessels and represent an alternate, dependable method to evaluate capillary perfusion.
Meat tenderizer in the acute treatment of imported fire ant stings.
Meat tenderizer containing the proteolytic enzyme papain was tested for therapeutic efficacy in the sting of the imported fire ant. The parameters of pain and itching were used to evaluate qualitatively the sting response in 22 healthy medical students, and the laser Doppler velocimeter was used to assess quantitatively the change in cutaneous blood flow. The results indicated that, during the acute-phase reaction, no clinically or statistically significant difference was found between stings treated with meat tenderizer and stings treated without tenderizer. Therefore we conclude that meat tenderizer is of no therapeutic value in the acute treatment of the imported fire ant sting.
