Clinical Information for Other diseases of lip and oral mucosa (K13)

Oral Submucous Fibrosis - Irreversible FIBROSIS of the submucosal tissue of the MOUTH.

Churg-Strauss Syndrome - Widespread necrotizing angiitis with granulomas. Pulmonary involvement is frequent. Asthma or other respiratory infection may precede evidence of vasculitis. Eosinophilia and lung involvement differentiate this disease from POLYARTERITIS NODOSA.

Eosinophilic Granuloma - The most benign and common form of Langerhans-cell histiocytosis which involves localized nodular lesions predominantly of the bones but also of the gastric mucosa, small intestine, lungs, or skin, with infiltration by EOSINOPHILS.

Kimura Disease - A chronic inflammatory disease characterized by benign enlargement of cervical LYMPH NODE and SALIVARY GLANDS with increased levels of IMMUNOGLOBULIN E. Unlike ANGIOLYMPHOID HYPERPLASIA WITH EOSINOPHILIA it involves eosinophil infiltrates in lymph node and salivary glands and mostly found in Asian males.

Leukoplakia, Oral - A white patch seen on the oral mucosa. It is considered a premalignant condition and is often tobacco-induced. When evidence of Epstein-Barr virus is present, the condition is called hairy leukoplakia (LEUKOPLAKIA, HAIRY).

Leukoplakia - A white patch lesion found on a MUCOUS MEMBRANE that cannot be scraped off. Leukoplakia is generally considered a precancerous condition, however its appearance may also result from a variety of HEREDITARY DISEASES.

Leukoplakia, Hairy - Epithelial hyperplasia of the oral mucosa associated with Epstein-Barr virus (HERPESVIRUS 4, HUMAN) and found almost exclusively in persons with HIV infection. The lesion consists of a white patch that is often corrugated or hairy.

Velopharyngeal Insufficiency - Failure of the SOFT PALATE to reach the posterior pharyngeal wall to close the opening between the oral and nasal cavities. Incomplete velopharyngeal closure is primarily related to surgeries (ADENOIDECTOMY; CLEFT PALATE) or an incompetent PALATOPHARYNGEAL SPHINCTER. It is characterized by hypernasal speech.

Cheilitis - Inflammation of the lips. It is of various etiologies and degrees of pathology.

Melkersson-Rosenthal Syndrome - An idiopathic syndrome characterized by one or more of the following; recurrent orofacial swelling, relapsing facial paralysis, and fissured tongue (lingua plicata). The onset is usually in childhood and relapses are common. Cheilitis granulomatosa is a monosymptomatic variant of this condition. (Dermatol Clin 1996 Apr;14(2):371-9; Magalini & Magalini, Dictionary of Medical Syndromes, 4th ed, p531)

Polyarteritis Nodosa - A form of necrotizing non-granulomatous inflammation occurring primarily in medium-sized ARTERIES, often with microaneurysms. It is characterized by muscle, joint, and abdominal pain resulting from arterial infarction and scarring in affected organs. Polyarteritis nodosa with lung involvement is called CHURG-STRAUSS SYNDROME.

Eosinophils - Granular leukocytes with a nucleus that usually has two lobes connected by a slender thread of chromatin, and cytoplasm containing coarse, round granules that are uniform in size and stainable by eosin.

Instructional Notations

Includes Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.

• epithelial disturbances of tongue

Use Additional Code Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.

• code to identify:
• alcohol abuse and dependence F10
• exposure to environmental tobacco smoke Z77.22
• exposure to tobacco smoke in the perinatal period P96.81
• history of tobacco dependence Z87.891
• occupational exposure to environmental tobacco smoke Z57.31
• tobacco dependence F17
• tobacco use Z72.0

Type 2 Excludes Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

• cysts of oral region K09
• diseases of tongue K14
• stomatitis and related lesions K12
