Atypical fibroxanthoma (== Template:IPA ==
The Template:IPA (International Phonetic Alphabet) is a system of phonetic notation based primarily on the Latin alphabet. It was devised by the International Phonetic Association in the late 19th century as a standardized representation of the sounds of spoken language.
Pronunciation
The pronunciation of the term "IPA" is /aɪ piː eɪ/ in English.
Etymology
The term "IPA" is an acronym for the International Phonetic Alphabet. The International Phonetic Association, founded in 1886, created the IPA to provide a single, universal system for the transcription of spoken language.

- Phonetics: The study of the physical sounds of human speech. It is concerned with the physical properties of speech sounds (phonemes), and the processes of their physiological production, auditory reception, and neurophysiological perception.
- Phonology: The study of the way sounds function within a particular language or languages. While phonetics concerns the physical production, acoustic transmission and perception of the sounds of speech, phonology describes the way sounds function within a particular language or languages.
- Transcription (linguistics): The systematic representation of spoken language in written form. The source of the words transcribe and transcription, the term means "to write across" in Latin, and it's the process of converting spoken language into written form.

Etymology
The term "atypical fibroxanthoma" is derived from the Greek words "atypikos" (not typical), "fibro" (fibrous tissue), "xanthos" (yellow), and "oma" (tumor). It refers to the unusual (atypical) nature of this tumor, which is composed of fibrous and xanthomatous (foamy) cells.
Definition
Atypical fibroxanthoma is a dermatological condition characterized by a rapidly growing, non-ulcerating nodule on sun-exposed skin. It is considered a variant of squamous cell carcinoma, but with less potential for metastasis.
Symptoms
The most common symptom of atypical fibroxanthoma is a rapidly growing, red or pink nodule on sun-exposed skin, particularly on the head and neck. The lesion may be smooth, crusted, or ulcerated.
Diagnosis
Diagnosis of atypical fibroxanthoma is primarily based on histopathological examination of a skin biopsy. The tumor cells are atypical and pleomorphic, with many showing xanthomatous changes.
Treatment
Treatment typically involves surgical excision with clear margins. Mohs micrographic surgery is often used due to its high cure rate. Radiation therapy may be used in cases where surgery is not possible.
Prognosis
The prognosis for atypical fibroxanthoma is generally good, as it rarely metastasizes. However, recurrence is possible, particularly if the initial excision was not complete.
