Neuroendocrine carcinomas of the larynx.

The clinical and histopathological characteristics of seven cases of Moderately Differentiated Neuroendocrine Carcinomas (MDNEC) and two cases of Poorly Differentiated Neuroendocrine Carcinomas (PDNEC) have been reviewed. The tumours arose in the supraglottis of predominantly elderly men. Two cases had raised levels of urinary 5-hydroxy-indole-acetic acid at presentation but no case developed the carcinoid syndrome. PDNEC were histologically identical to the oat cell type carcinoma of the bronchus and were associated with an extremely aggressive clinical course with both patients dying of widespread metastases within one month of registration. MDNEC also metastasized frequently with four of seven cases dying with widespread disease. The tumours have previously been reported as not being radiosensitive; however three cases remain free of disease following biopsy and radiotherapy alone. The place of radiotherapy in the management of these tumours is discussed.

Sarcomas in north west England: I. Histopathological peer review.

A total of 468 cases of bone, soft tissue and visceral sarcomas (and certain other tumours) diagnosed during the years 1982-84 in North West England were entered in a study of histopathological peer review, incidence and survival. This paper describes the effects of peer review. Material was reviewed by a panel of five pathologists for 413 of the 450 cases originally registered as sarcomas with the Regional Cancer Registry. The diagnosis of sarcomas was confirmed in 76% cases and and there was agreement on sub-type for 53% cases. Measures of agreement were lowest for the two sub-types most commonly diagnosed i.e. malignant fibrous histiocytoma and leiomyosarcoma. Degree of agreement between individual pathologists and final panel diagnosis was also very variable but never less than 65%. It is concluded that second opinion is essential in cases of presumed sarcomas for studies of incidence and aetiology and to ensure that appropriate treatment is selected.

Sarcomas in north west England: II. Incidence.

Incidence data on a population-based series of bone, soft tissue and visceral sarcomas from the North West of England are presented. The data are derived mainly from a total of 429 cases registered with the North Western Regional Cancer Registry and diagnosed during the period 1982-84, 76% of which were confirmed as sarcomas by a panel of five pathologists. Overall incidence of confirmed sarcomas per million person years was slightly higher in females (26.81) than in males (24.71) but there was no sex difference when 38 non-reviewed cases were taken into consideration (females 29.07, males (28.83). After exclusion of tumours of female genital tract, incidence of soft tissue tumours was very similar in both sexes (females 18.25, males 18.70). Bone tumours were almost twice as frequent in males (6.01) as in females (3.55).

Monocytoid B cell lymphoma.

The clinical, light microscopic, ultrastructural, immunocytochemical and cytogenetic features of a case of monocytoid B cell lymphoma were investigated. The tumour initially affected the cervical and supraclavicular nodes, but 33 months later affected the left parotid salivary gland. The patient had subclinical Sjögren's syndrome. The neoplastic cells showed characteristic morphological features and had peri- and interfollicular distribution in the node. Immunocytochemically the tumour cells were L26, 4KB5, MB2, CD19, CD20, CD22 and IgM/kappa positive. Prominent plasmablastic plasmacytoid differentiation was present in the recurrent tumour, suggesting an origin from post-follicular B cells. The lymphoma cells showed unusual cytogenetic abnormalities.

Twelve cases of Ki-1 positive anaplastic large cell lymphoma of skin.

In seven of 12 cases of Ber-H2 (Ki-1) positive anaplastic large cell non-Hodgkin's lymphoma (Ki-1 ALCL) disease remained localised to skin, and in five there was extracutaneous spread. Four patients had histological evidence of pre-existing or coexisting mycosis fungoides, and three patients had a long standing history of eczema or ichthyosis. In two cases the presence of a T phenotype was shown in frozen sections, and in a further six cases a T phenotype was firmly established in paraffin wax sections. Four patients died less than one year after presentation (two with disseminated lymphoma; two from other causes); one died at five years with widespread lymphoma and the remaining seven cases were alive one to 14 1/2 years after presentation. Three of the four patients with associated mycosis fungoides had prolonged survival, contrary to the findings of previous reports which suggest secondary Ki-1 ALCL behaves aggressively. The recognition of these tumours is important because of their relatively good prognosis. The diagnosis can be readily substantiated immunohistochemically, using a simple panel of antibodies.

Short term effect of diltiazem on portal hypertension in patients with non-cirrhotic portal fibrosis.

Fourteen patients of non-cirrhotic portal fibrosis (NCPF) with portal hypertension were put on oral diltiazem hydrochloride (90 mg/day) or placebo on a prospective, randomised, single blind basis for 15 days. Predrug hemodynamic and biochemical status were similar in both groups. Diltiazem produced significant reduction (p less than 0.001) in mean intrasplenic pressure: from 41.88 (SD +/- 6.18) to 21.5 (+/- 7.91) cm of normal saline as against 45.56 (+/- 9.45) to 43.33 (+/- 8.27) in the placebo group. Mean arterial pressure (MAP), heart rate and cardiac output (CO) did not change in either group. Thus, the calcium channel blocker diltiazem reduces portal pressure in patients with NCPF, independent of reduction in MAP and CO; this is advantageous in situations where compromised cardiac hemodynamics may prove deleterious.

Conservation of the breast using two different radiotherapy techniques: interim report of a clinical trial.

Patients with a clinically palpable breast carcinoma, 4 cm or less in diameter, and with no palpable nodes in the axilla were prospectively entered into a randomized clinical trial. A total of 713 patients were registered between November 1982 and December 1987, of whom 708 are evaluable at a median follow-up of 37 months. Following excision of the primary tumour, patients were randomly allocated either to have radiotherapy to the affected quadrant only (LF group) or to the whole breast and regional lymph node areas (WF group). No adjuvant hormone or chemotherapy was prescribed. The primary tumour was reported as completely excised histologically in 80% of cases, incompletely excised in 10%, and no estimate was possible in 10%. At six years from first randomization, 96% of the WF group and 92% of the LF group have remained free of breast recurrence (94% and 87% actuarial breast recurrence-free survival at 5 years). Part of the difference may be explained by the 20% recurrence rate in the breast for lobular carcinomas treated within the LF group. Of the WF group 14 patients (4%) developed recurrent disease in the axilla, compared to 50 patients (14%) in the LF group (95% and 86% actuarial axillary recurrent-free survival at 5 years). Patients with primary tumours histologically 1 cm or less in diameter had a 98% actuarial 5-year survival compared with 74% for those with tumours measuring 2 cm or more in diameter (P = 0.003). Continued follow-up of these patients will provide further information on the factors governing local/regional recurrence.

The ultrastructure of epithelioid sarcoma.

We have described clinical, histological immunohistochemical and ultrastructural features of four typical examples of epithelioid sarcoma. Smooth-muscle-type focal densities amid fine actin-like filaments in typical epithelioid cells often containing prominent rER have been observed, as well as a structure in the form of a densely granular cytoplasmic body. These features are suggestive of myofibroblastic differentiation. A tumour with light microscopy features typical of epithelioid sarcoma but of spindle-cell appearance is also described. Ultrastructurally this consists of myofibroblasts and it is suggested that this may be an unusual variant in which myofibroblastic differentiation is a major feature.

Randomized study of Corynebacterium parvum adjuvant therapy following surgery for (stage II) malignant melanoma.

One hundred and fifteen patients with histologically proven primary cutaneous melanoma were entered into a randomized prospective study following surgical removal of clinically obvious regional metastases. The study started in 1977 and was completed in June 1982. Fifty-eight patients (10 with regional skin metastases and 48 with regional node metastases) were in the control group and 57 (15 regional skin, and 42 regional node metastases) received adjuvant C. parvum. Other clinical features were well balanced for each group. C. parvum, 2 mg/m2 IV was repeated eight times at three weekly intervals. The schedule was based on previous work which indicated significant increase in killer cell activity. There was no serious toxicity and 22 patients exhibited tachyphylaxis. Seventeen patients in the control group (11 tumour free) are alive at 24-80 months, and 20 patients in the C. parvum group (12 tumour free) are alive 24-76 months from randomization. No statistically significant difference (P greater than 0.05) was observed between the two patient groups for overall survival (median 26 months) or relapse free survival (median 8 months) from the date of randomization. Nor was the overall survival from the date of primary surgery (median 52 months, range 4-237) or the relapse free survival, median 28 months, range 2-225, significantly different between the two groups of patients. The relapse pattern in the two groups, and survival after relapse were no different though the response rate to actinomycin D and DTIC chemotherapy was significantly higher in the control (48 per cent) than in the C. parvum (23 per cent) group. Toxicity to chemotherapy was not significantly affected by previous C. parvum treatment. Although there were trends for better survival, in the C. parvum patient group, statistically significant activity has not been noted in this study.

Female type cystic hyperplasia in a male breast.

A 28 year old man had a swelling of the right breast. He was phenotypically and karyotypically a normal male. Microscopic examination of the excised specimen showed the pattern of cystic hyperplasia identical to that commonly seen in the female breast. Numerous cysts were grouped in a lobular pattern and their lining showed apocrine metaplasia. There was extensive background fibrosis, some mammary duct ectasia and some features consistent with the more classical microscopic appearances of gynaecomastia. Whilst some of the features noted above are sometimes seen in gynaecomastia the presence of the full range of the features of cystic hyperplasia is distinctly unusual in the male.

Primary lymphoma of the penis.

Two cases of primary lymphoma of the penis are described. The penis is an extremely uncommon site for primary lymphoma and it may easily be confused with the commoner squamous cell carcinoma. It is important to make the distinction however since lymphoma will respond well to local low dose irradiation as in these cases without the need for mutilating surgery.

Crohn's disease of the gall bladder.

A 64 year old man with known enteric Crohn's disease developed a granulomatous cholecystitis in which the histological features were identical to those seen in sites conventionally affected by this disease. Extraintestinal granulomatous lesions are rare in Crohn's disease and the present case is reported because of its apparent uniqueness.
