New primary nonmelanoma skin cancer in patients with a history of squamous cell carcinoma of the skin. Implications and recommendations for follow-up.

BACKGROUND: Rational follow-up guidelines for skin cancer patients should be based on the risk of three separate events: cancer recurrence, cancer metastasis, and the development of subsequent skin cancers. However, currently no guidelines exist for follow-up of patients with squamous cell carcinoma of the skin (SCC), which take into account all three of these risks. OBJECTIVE: The purpose of this study is to establish rational minimum guidelines for follow-up of patients with SCC. To do this, we first must determine the risk of SCC patients for the development of subsequent skin cancers. Combining these data with previously published data on SCC recurrence and SCC metastasis, we then propose guidelines for follow-up of patients with SCC. METHODS: We followed up 101 SCC patients on a yearly basis for 5 years after treatment and recorded the date and site of subsequent nonmelanoma skin cancers (NMSCs). RESULTS: Thirty percent of SCC patients developed additional SCCs and 52% developed subsequent NMSCs within 5 years of therapy for their first SCC. Patients showing the highest risk of subsequent NMSC were those presenting with multiple SCC, SCC greater than 1 cm in diameter, SCC requiring more than 1 Mohs surgery layer to remove, or SCC occurring on the scalp, ear, nose, or extremities. One hundred percent of subsequent NMSCs were detected by the fourth year of follow-up; 54% of these occurred within the first year of follow-up. CONCLUSION: After combining our data with previously published studies of SCC recurrence and metastasis, we recommend that all patients with SCC be followed up for at least 4 years after treatment. Moreover, because most subsequent NMSCs, SCC recurrences, and SCC metastases developed early in the follow-up period, we recommend that patients be reexamined at least every 3 months during the first year of follow-up and every 6 months thereafter. It must be stressed that these are meant as minimum follow-up guidelines.

Hendersonula toruloidea infection in man. Index cases in the non-endemic North American host, and a review of the literature.

Hendersonula toruloidea (HT) is a dematiaceous fungus that is an endemic human pathogen in tropical and subtropical countries. Infection with this fungus is often clinically indistinguishable from Trichophyton rubrum or other dermatophytoses. However, because HT will not grow on standard cycloheximide containing fungal media, and because HT is usually resistant to standard anti-fungal therapies, we believe that HT is a more common cause of 'recalcitrant dermatophytosis' in the United States than is currently recognized. HT may be especially prevalent among immigrant patients from endemic countries. We report the first cases of HT to occur in a non-endemic region of the United States. This suggests that HT may become a significant pathogen in the native American host as well. Moreover, we report the first case of a tinea capitis-like infection due to HT.

The use of a combination skin hook and tissue forceps: a new instrument for dermatologic surgery ("Frankel-Adson forceps").

The dermatologic surgeon frequently uses both skin hook and tissue forceps to accomplish atraumatic wound closure. Since this requires the surgeon to change instruments frequently during the course of the procedure, a combination skin hook and tissue forceps has been developed to make possible the simultaneous use of these two instruments. In addition, using a new technique that combines the two capabilities of this instrument, the surgeon can further reduce the risk of tissue trauma during surgery. The instrument and this technique are described.

Acral lividosis--a sign of myeloproliferative diseases. Hyperleukocytosis syndrome in chronic myelogenous leukemia.

Acral ischemia with lividity is a well-described dermatologic sign in the myeloproliferative diseases polycythemia vera and essential thrombocythemia. It has not previously been reported as a sign of chronic myelogenous leukemia (CML). We suggest the term acral lividosis to describe this clinical entity in patients with any myeloproliferative disease. We propose that the pathophysiology of acral lividosis in CML involves occlusion of small blood vessels of the skin by large, nondeformable myeloblasts, a process that has been shown histologically to occur in other organs in patients with CML. This process, called leukostasis, occurs in patients with CML who have over 50.0 X 10(9)/L (50,000/mm3) circulating myeloblasts. Patients manifest cardiorespiratory and central nervous system compromise, a clinical constellation known as the hyperleukocytosis syndrome. Acral lividosis occurred in a patient with CML in whom nearly every organ demonstrated leukostasis on autopsy.

Oral Crohn's disease: report of two cases in brothers with metallic dysgeusia and a review of the literature.

Between 4% and 14% of patients with intestinal Crohn's disease (CD) may manifest the typical oral changes of this disorder. These changes include labial and intraoral inflammatory tissue hyperplasia with fissuring ("cobblestoning") and swelling. In addition, angular cheilitis and regional lymphadenopathy may be present. We report two cases of oral CD in brothers, in whom the unusual symptoms of metallic dysguesia and gingival bleeding were prominent features. Despite the well-recognized familiar incidence of CD, a review of the literature shows that in no previous case reports has familial oral CD been noted. Successful symptomatic and objective treatment results were obtained with a mouthwash preparation of triamcinolone acetonide, tetracycline, and lidocaine.
