Malignant Neoplasms Of Lip And Oral Cavity Or Pharynx – Definitions & ICD 11 Codes


Definition of Malignant Neoplasms Of Lip And Oral Cavity Or Pharynx: Squamous cell carcinomas amount to more than 90% of malignant tumours of the oral cavity and oropharynx. As in other parts of the upper aerodigestive tract, there is a strong and synergistic association with tobacco smoking and alcohol abuse. In some regions, particularly the Indian subcontinent, oral cancer is among the most frequent malignancies, largely due to tobacco chewing.

Exclusions:


Malignant neoplasms of lip

Definition of Malignant neoplasms of lip: Malignant neoplasms originating from the transitional epithelium of the lip (excluding oral mucosa and skin of the outer lip) or from the underlying anatomical structures (e.g. orbicularis oris muscle).

2B66.Z Malignant neoplasms of other or unspecified parts of mouth unspecified

Definition of Malignant neoplasms of other or unspecified parts of mouth unspecified: Salivary gland tumours can show a striking range of morphological diversity between different tumour types and sometimes within an individual tumour mass. In addition, hybrid tumours, dedifferentiation and the propensity for some benign tumours to progress to malignancy can confound histopathological interpretation. These features, together with the relative rarity of a number of tumours, can sometimes make diagnosis difficult, despite the abundance of named tumour entities. The increasing use of pre-operative fine needle aspiration biopsies also needs to be taken into account, as artifactual changes may be superimposed on the tumours. Unfortunately, the morphological variability of these tumours is mirrored by the immunocytochemical profiles, so that special stains are rarely useful in routine diagnosis of salivary gland epithelial neoplasms.

Exclusions:

2B6A.0 Squamous cell carcinoma of oropharynx

Definition of Squamous cell carcinoma of oropharynx: A squamous cell carcinoma arising from the oropharynx. It predominantly affects adults in their fifth and sixth decades of life and is associated with alcohol and tobacco use. Human papillomavirus is present in approximately half of the cases. It is characterised by a tendency to metastasize early to the lymph nodes. When the tumour is small, patients are often asymptomatic. Physical examination may reveal erythematous or white lesions or plaques. The majority of patients present with locally advanced disease. Signs and symptoms include mucosal ulceration, pain, bleeding, weight loss, neck swelling, and difficulty speaking, chewing, and swallowing. Patients may also present with swollen neck lymph nodes without any symptoms from the oropharyngeal tumour. The most significant prognostic factors are the size of the tumour and the lymph nodes status.

2B6A.Y Other specified malignant neoplasms of oropharynx

2B6A.Z Malignant neoplasms of oropharynx unspecified

Definition of Malignant neoplasms of oropharynx unspecified: A wide variety of tumours can arise in the nasopharynx, but it is nasopharyngeal carcinoma that has fascinated generations of oncologists, pathologists, scientists and epidemiologists. It shows marked geographic differences, with highest incidence rates in Southern Chinese. In some endemic areas, the incidence has declined by about 30% over the past two decades, suggesting that environmental or lifestyle factors may play a major role and that the disease is, to some extent, preventable. Nasopharyngeal carcinoma shows a very strong association with Epstein-Barr virus (EBV) infection, irrespective of the ethnic origin of the patients. This association has pioneered a new paradigm of utilizing viral serological tests for the diagnosis of cancer and for screening in high-risk populations. Naso -pharyngeal carcinoma is generally responsive to radiation therapy, and the clinical outcome has greatly improved over the years, due to refinements in staging and to improved therapy protocols. The unusual and often deceptive histological features of nasopharyngeal carcinoma have generated controversies over the nature of the tumour and still pose a challenge to surgical pathologists. There have possibly been more names invented for the various histological subtypes of nasopharyngeal carcinoma than any other tumour type.
