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.
Two cases of digitate dermatosis are presented. The clinical and histopathologic features of this unique entity are reviewed. We suspect that digitate dermatosis may be more prevalent than reported.
A case of tuberculoid leprosy, undiagnosed and consequently untreated for four years, is presented. This case report is presented in an attempt to alert the clinician to the occurrence of leprosy in American population and to raise the index of suspicion in the proper clinical setting.
A 71-year-old man with a penile verrucous carcinoma presenting as a large cutaneous horn is described. Both verrucous carcinoma and penile cutaneous horn are relatively uncommon entities and have not been previously reported to occur concomitantly. A brief review of the relevant medical literature and methods of therapy is included.

Our objective was to establish the aerobic and anaerobic microbiology of nonbullous impetigo (NI) in children. We used a retrospective review of clinical microbiology laboratory and patients' records. Specimens were obtained from 40 patients with NI lesions and showed bacterial growth. Aerobic or facultative anaerobic bacteria only were present in 24 patients (60%), strict anaerobic bacteria only in 5 patients (12.5%), and mixed anaerobic-aerobic flora was present in 11 patients (27.5%). Sixty-four isolates were recovered (1.6 per specimen): 43 aerobic or facultative, and 21 anaerobic. The predominant aerobic and facultative bacteria were Staphylococcus aureus (29 isolates), Group A beta hemolytic streptococcus (GABHS) (13 isolates), and Escherichia coli (1 isolate). The predominant anaerobes were Peptostreptococcus spp. (12), pigmented Prevotella spp. (5), Fusobacterium spp. (2), and Bacteroides fragilis (1). Single bacterial isolates were recovered in 17 patients (42.5%), 13 of which were S. aureus. S. aureus alone or mixed with GABHS or Peptostreptococcus spp. were isolated from all body sites. Mixed flora of Peptostreptococcus spp. with Prevotella spp. or Fusobacterium spp. was mostly found in infections of the head and neck, while E. coli mixed with B. fragilis and Peptostreptococcus spp. were isolated from one infection of the buttocks area. Thirty-three organisms isolated from 32 patients (80%) produced the enzyme beta-lactamase. This study demonstrates the polymicrobial aerobic-anaerobic microbiology of NI lesions.
