Follow-up in stage I cutaneous malignant melanoma: an audit.

In Southampton, follow-up of patients with malignant melanoma is carried out in a single dedicated clinic. An audit has been performed to assess its objective value in diagnosing and treating tumour relapse and its subjective value as perceived by patients. Over a 10-year period, of 331 patients with Stage I disease 65 (20%) have developed tumour recurrence. Fifty-five first relapses were either local or in regional lymph nodes, and thus potentially curable; half were found within 3 months of the previous clinic visit. Seventy-two per cent of local and 47% of nodal recurrences were either symptomatic or detected initially by the patient. Whilst doctor-diagnosed nodal recurrences tended to be smaller and to involve fewer histologically positive nodes, subsequent survival was identical in those with patient-diagnosed nodal recurrences. The clinic makes inefficient use of medical time. Questionnaire responses indicate that 54% of patients suffer anxiety prior to clinic visits. Nevertheless follow-up was considered worthwhile by 95% of patients and regular visits were preferred to a 'walk in when necessary' system. The clinic appears to have an important educational role. A series of changes to current follow-up practice are proposed including: more frequent visits for high risk patients, changes in clinic personnel, and greater emphasis on patient education and self examination.

Successful treatment of steatocystoma multiplex by simple surgery.

Steatocystoma multiplex is usually a minor cosmetic problem but rarely can be extremely disfiguring. Unfortunately, the very patients who would benefit most from treatment are usually regarded as having too may cysts for surgery. We report a case of extensive steatocystoma multiplex which was treated by a simple surgical technique under general anaesthetic.

Streptococcal necrotising fasciitis: comparison between histological and clinical features.

Nineteen acute and 17 subacute cases of necrotising fasciitis due to beta haemolytic streptococci are described. Excised tissue from seven and four cases, respectively, was available for histological examination. The two clinical types showed remarkable similarities, with inflammation and necrosis from epidermis to subcutaneous fat. Haemorrhage was present in variable amounts in both types. Gram positive cocci were not always identified in tissue, nor cultured, when serological tests were required to confirm the diagnosis. The only apparent difference between the acute and subacute type was the higher incidence of thrombi in some blood vessels of acute cases, whereas patent vessels or recanalized thrombus were usually found in subacute cases. This quantitative difference in the degree of thrombosis may alone be responsible for the varying clinical features and response to antibiotics.

Treatment of basal-cell carcinoma: comparison of radiotherapy and cryotherapy.

A prospective randomised trial to compare radiotherapy and cryotherapy in the treatment of basal-cell carcinomas was carried out in 93 patients. Two years after treatment, 4% of tumours treated with radiotherapy and 39% of those treated with cryotherapy had recurred. It is concluded that cryotherapy does not offer a satisfactory alternative to radiotherapy in the treatment of basal-cell carcinomas.

Ulceration of the lip associated with a 'calibre-persistent artery'.

A case of ulceration of the lower lip, associated with a 'calibre-persistent artery', is presented. The lesion was diagnosed clinically as squamous cell carcinoma and excised accordingly. 'Calibre-persistent artery' is not a widely known entity, has not been described previously in the dermatological literature and should be sought in any lip ulcer of obscure aetiology.

The value of bacteriology and serology in the diagnosis of cellulitis and erysipelas.

Patients diagnosed as suffering from erysipelas or cellulitis were subjected to bacteriological and serological investigations. The serological tests used included the anti-streptolysin O reaction (ASO), the anti-deoxyribonuclease B test (ADB) and the anti-hyaluronidase tests (AHT) that are specific both for the group A streptococcus (Streptococcus pyogenes) and for the human pyogenic streptococci of group C or group G. Antibody tests to the alpha-lysin and the nuclease of Staphylococcus aureus were also employed. Conventional bacteriological culture methods were used plus needle aspiration of injected saline in most patients with erysipelas, but recognized pathogens were isolated in only 42% of cases. Our results indicate the limitations of these tests for making initial diagnoses and deciding treatment. Serial serological testing was very successful in differentiating cellulitis due to group A, C or G haemolytic streptococci, or occasionally Staphylococcus aureus, but was positive in only 40% of cases of erysipelas.

The value of bacteriology and serology in the diagnosis of necrotizing fasciitis.

Fourteen patients with necrotizing fasciitis are described. In thirteen the cause was Streptococcus pyogenes [Group A beta haemolytic streptococcus (BHS)]; in the fourteenth, Staphylococcus aureus was responsible. In the acute fulminating form of the disease, BHS can be cultured from the affected tissues. In the less acute form, particularly when the patient has been previously treated with antibiotics, other bacteria colonize the tissues and the BHS cannot be isolated. Serological evidence of infection with Streptococcus pyogenes can be ascertained in all such patients by finding high levels of anti-desoxyribonuclease B and anti-hyaluronidase. Measurement of the anti-streptolysin O titre is not helpful. Once the diagnosis is made, surgical removal of all necrotic tissue is still the treatment of choice.

Fungal diseases in Shiraz.

In 122 patients with fungal diseases studied over a six month period, sixty were seen with dermatophyte infections. Tinea pedis, cruris and ungruium occurred mainly in adult males attending the private hospital and tinea corporis and capitis children attending the University Hospital. The organisms found were Trichophyton rubrum, T. mentagrophytes, T. schonleinii, T. tonsurans, Epidermophyton floccosum and Microsporum canis. Infections with Candida albicans occurred both in the urban and rural population and included case of familial chronic muco-cutaneous candidiasis. Pityriasis versicolor was the commonest fungal disease seen.

The bacteriology of skin cysts.

Thirty-nine clinically uninflamed cysts of the three most common varieties, epidermoid cysts, trichilemmal cysts and steatocystoma multiplex were removed under sterile conditions and the contents cultured under aerobic and anaerobic conditions. Seventy-three percent of epidermoid cysts grew significant numbers of organisms whereas none of the trichilemmal cysts did so. The organisms found were the common skin commensals, Staphylococcus epidermidis biotype I, anaerobic Gram positive cocci of the Gaffya type and Corynebacterium acnes Type I. This indicates that cysts which clinically have a punctum, namely epidermoid cysts, may become colonized with surface bacteria under normal circumstances. If they become colonized with pathogenic bacteria they become inflamed, a not uncommon clinical picture. The results from patients with steatocystoma multiplex were difficult to interpret because of the small numbers of patients involved and the unusual clinical appearance they presented.

Trichilemmal cysts arising in an extensive comedo naevus.

A 25-year-old male is described who had extensive linear comedo naevi present from birth, involving the face, both sides of the trunk, both arms, one palm, both legs and one sole. Within these lesions multiple trichilemmal cysts were arising giving rise to a zosteriform pattern of skin nodules. Both lesions were confirmed histologically. It is suggested that comedo naevus is a hamartomatous abnormality of the hair follicle in which all layers, including the external root sheath, are involved and from which trichilemmal cysts may arise.
