Two cases of achalasia of the lower third of the oesophagus are presented. Leucoplakia was encountered in one of the cases. The clinical, aetiopathogenic and x-ray diagnostic aspects of achalasia are described in relation to the possibility that it may be associated with neoplasia or pre-cancerous alterations. In both the above cases, early dysphagia was encountered.

A retrospective analysis of direct laryngoscopies performed at our institution in 1978 was undertaken utilizing computer technology. The population which consisted of 54% males and 46% females had an average age of 50.4 years. The most common symptom was hoarseness (83.6%). The most frequent benign and malignant diagnoses were vocal cord polyp and squamous cell carcinoma, respectively. Males predominated in all disease entities except vocal cord polyps. Benign disease entities presented most frequently with one or two symptoms, while malignant pathology presented with a varied array and number of symptoms. The indications: "tumor" seen on indirect laryngoscopy, sore throat, dysphagia, otalgia, upper respiratory tract obstruction, hemoptysis, cough and leukoplakia were most frequently associated with malignancy. Voice abuse occupations were most commonly associated with vocal cord polyps and tobacco and alcohol use was most frequently associated with laryngeal cancer. Eighty-five percent of direct laryngoscopies were done under general anesthesia with two-thirds utilizing direct suspension microlaryngoscopy.

Although esophageal strictures with attendant malignant degeneration are well known sequelae of caustic ingestion, fixed pharyngeal structural lesions and development of oral leukoplakia are not well appreciated consequences of such ingestion. We present a patient 12 yr after lye ingestion who displayed rapidly progressive dysphagia suggestive of esophageal carcinoma. Instead, adhesions bisecting the cricopharyngeal inlet and an upper esophageal stricture were found endoscopically. In addition, an area of hypopharyngeal leukoplakia with marked acanthosis, parakeratosis, and dysplasia was noted and resected. The management of this patient's dysphagia and subsequent follow-up for his potentially precancerous oral lesion form the basis of this report.

Oral cancer is an important health issue. The WHO predicts a continuing worldwide increase in the number of patients with oral cancer, extending this trend well into the next several decades. In the US the projected number of new cases of oral and oropharyngeal cancer will exceed 31,000 per year. Mortality due to cancers in this region exceeds the annual death rate is the US caused by either cutaneous melanoma or cervical cancer. Significant agents involved in the etiology of oral cancer in Western countries include sunlight exposure, smoking and alcohol consumption. Use of the areca or betel nut in many cultures is a major etiological factor outside of the USA. Other etiologic factors associated with oral squamous cell carcinoma, but far less significant statistically, include syphilis and sideropenic dysphagia. Recently, strong evidence for an etiological relationship between human papilloma virus and a subset of head and neck cancers has been noted. It is generally accepted that most sporadic tumors are the result of a multi-step process of accumulated genetic alterations. These alterations affect epithelial cell behavior by way of loss of chromosomal heterozygosity which in turn leads to a series of events progressing to the ultimate stage of invasive squamous cell carcinoma. The corresponding genetic alterations are reflected in clinical and microscopic pathology from hyperplasia through invasiveness. A wide range of mucosal alternations fall within the rubric of leukoplakia. Proliferative verrucous leukoplakia represents a relatively new type of leukoplakia that is separate from the more common or less innocuous form of this condition. Erythroplakia is particularly relevant considering its almost certain relationship with dysplasia or invasive carcinoma. Squamous cell carcinoma will develop from antecedent dysplastic oral mucosal lesions if an early diagnosis has not been made and treatment given. Early diagnosis within stages I and II correspond to a vastly improved 5-year survival rate when compared with more advanced stage III and IV lesions. Surgical management of this disease remains the mainstay of treatment. Other therapies include radiation and chemotherapy options that may be used adjunctively and palliatively. Following treatment, it is important to understand the significant risks of second primary cancers developing within the upper aerodigestive tract as a result of field cancerization. The most important message is that early detection of the asymptomatic early stage oral cancer translates in general terms to satisfactory clinical outcome and cure in most patients.

Leukoplakia means a " White Patch", and is defined as a white patch or plaque on the mu-cosa that cannot be rubbed off and is not ascribable to any other condition(Fig. 1). Many patients come to the O.P.D. with presentation of white patch, ulcer, excessive salivation, trismus, increased sensitivity to chilies and burning sensation, dysphagia, otalgia and ultimately growth. Advanced countries have attained sophistication in oncopathy (like tumor marker, tumor antibodies). But we are still in search of an efficient screening method by which the cytologist can point accurately towards the nature of the disease within a few hours. That is why a correlative study of clinical picture and cytohistopathological findings had been studied in 74 cases in last three years, which were clinically diagnosed as leukoplakia in the out patient department of ENT in M.L.B. Medical College. Jhansi. In oral malignancy, it is extremely desirable that a correct and reliable method is adopted for early diagnosis and treatment, which can be instituted at a stage when the chances for cure are definitely greater.

The diagnosis of fungal laryngitis is often overlooked in immunocompetent patients because it is commonly considered a disease of the immunocompromised. Further confusion is caused by clinical and histological similarity to more common conditions like Leukoplakia. Demonstration of hyperkeratosis particularly if associated with intraepithelial neutrophils on biopsy should trigger a search for fungus using specialized stains. These patients usually present with hoarseness of voice. Pain is present inconsistently along with dysphagia and odynophagia. We present three cases of fungal laryngitis in immunocompetent patients out of which one underwent microlaryngeal surgery with excision biopsy. All these patients responded well with oral antifungal therapy.
