RESUMO
BACKGROUND: Sentinel lymph node (SLN) biopsy originally was described as a means of identifying lymph node metastases in malignant melanoma and breast carcinoma. The use of SLN biopsy in patients with oral and oropharyngeal squamous cell carcinoma and clinically N0 necks was investigated to determine whether the pathology of the SLN reflected that of the neck. METHODS: Patients undergoing elective neck dissections for head and neck squamous cell carcinoma accessible to injection were enrolled into our study. Sentinel lymph node biopsy was performed after blue dye and radiocolloid injection. Preoperative lymphoscintigraphy and the perioperative use of a gamma probe identified radioactive SLNs; visualization of blue stained lymphatics identified blue SLNs. A neck dissection completed the surgical procedure, and the pathology of the SLN was compared with that of the remaining neck dissection. RESULTS: Sentinel lymph node biopsy was performed on 40 cases with clinically N0 necks. Twenty were pathologically clear of tumor and 20 contained subclinical metastases. SLNs were found in 17 necks with pathologic disease and contained metastases in 16. The sentinel lymph node was the only lymph node containing tumor in 12 of 16. CONCLUSIONS: The SLN, in head and neck carcinomas accessible to injection without anesthesia, is an accurate reflector of the status of the regional lymph nodes, when found in patients with early tumors. Sentinel lymph nodes may be found in clinically unpredictable sites, and SLN biopsy may aid in identifying the clinically N0 patient with early lymph node disease. If SLNs cannot be located in the neck, an elective lymph node dissection should be considered.

The following case report describes a patient who is known to have both fibrous dysplasia and Paget's disease, and traces his history over more than 50 years. The similarities and differences between the two conditions and their relative importance at the various stages of the history are discussed.

OBJECTIVE: To study articular symptoms in relapsing polychondritis (RP) and their relationship to other clinical manifestations and prognosis. METHODS: Fourteen patients who met the diagnostic criteria proposed by Damiani and Levine for RP were studied. Clinical symptoms were recorded and laboratory and radiologic examinations were carried out. In one patient a synovial histology was obtained. RESULTS: Twelve patients had joint symptoms affecting the peripheral joints (9), the chondrocostal junctions (5), or both sites together (2). Peripheral arthritis was the most frequent finding, affecting 6 patients, while peripheral arthralgia was the only articular manifestation in 3 patients. The development of joint symptoms (arthralgia, arthritis and costochondritis) was unrelated to the appearance of chondritis at other sites and no correlation was found between articular involvement and age at onset, duration of the disease, number of flares, or severity of the disease, either in terms of the number of organs involved or fatal outcome (p > 0.05). However, when articular symptoms were analysed separately arthritis was associated with a longer duration (50 months vs 30), more affected organs (4.5 vs 3.3) and a poorer prognosis compared with patients with arthralgias alone or chondrocostal symptoms. CONCLUSION: Articular symptoms are common in RP but the presence of peripheral arthritis is associated with widespread disease and a poorer prognosis.

The clinical and histological features of 'mechanic's hands' are described in a patient with polymyositis characterized serologically by antibodies to histidyl tRNA synthetase (Jo-1). Although described in the past in association with polymyositis, these distinctive cutaneous lesions have only recently been associated with the 'anti-synthetase syndrome'. It is becoming apparent that recognition of subsets within the spectrum of polymyositis/dermatomyositis characterized by certain clinical and serological features not only have prognostic significance, but also may provide insights into mechanisms of disease.

A case of cutaneous T-cell lymphoma is presented in which the diagnosis was obscured by a concomitant granulomatous infiltrate. A working diagnosis of tuberculosis delayed appropriate treatment for several months over which time rapid progression of the disease was seen. Inclusion of overlying skin in the repeat biopsies yielded the histological information to establish the correct diagnosis and there was rapid regression on completion of a course of radiotherapy.

Verrucous carcinoma is a rare type of squamous cell carcinoma which is most often seen in the oral cavity and larynx. This paper describes a case of verrucous carcinoma of the maxillary antrum, a site in which this tumour has been described on only two previous occasions in the English language literature.

Using a standard technique involving monoclonal antibodies against T-cell subsets, we have shown that almost all the infiltrating T-cells in the epidermis of a patient with Pagetoid reticulosis (PR), one with epidermotropic mycosis fungoides (EMF) and one with poikiloderma atrophicans vasculare (PAV), were OKT8 positive (presumed cytotoxic/suppressor) T-cells. The infiltrating T-cells in the epidermis of a patient with limited plaque stage mycosis fungoides (MF), however, were almost exclusively Leu 3a-positive (presumed helper/inducer) T-cells as is usually found in this condition. The keratinocytes in the patients with PR, EMF and PAV were HLA-DR-positive whilst those in the patient with MF were HLA-DR-negative. We consider these four diseases to be part of the spectrum of mycosis fungoides, the first three conditions representing the early or benign end of the spectrum.

The pathology and histology are reported of five Scots who died of severe pneumonic illnesses after holidays in Spain, three in 1973 and two in 1977. There is strong evidence in favour of all the deaths having been due to the newly discovered Legionnaires' disease (LD) agent. The agent (or its soluble antigen) has been visualised in sections of lung tissue by fluorescent-antibody tests in all cases, and the agent has been identified by the Dieterle silver staining method in small numbers in all cases. Serological testing was possible in three of the patients, and two had very high antibody titres against the LD agent. Apart from the extensive and severe nature of the pathological process there is no feature to distinguish pulmonary infection by this agent from that due to more commonly known bacteria capable of causing lobar pneumonia. The severity and extensive nature of the process is partly a reflection of neglect in seeking treatment until late in the infection, and partly a reflection, as revealed in retrospect, on the use of the wrong antibiotic combination during treatment. Erythromycin has been recommended by other workers as the drug of choice against the LD agent. Infection by this organism is not confined to the USA or to Spain and is indigenous also in the United Kingdom.
