The outcome of the prognosis is dependent on early diagnosis and complete resection. The standard duration between diagnosis and reappearance was "23 months, 50 months, and 66 months for local recurrence, nodal metastasis, and distant metastasis, [respectively]" (Watarai, Amoh, Aki, Takasu, Katsuoka, 2011). In terms of prognosis regarding recorded patients, "27% of patients died from their disease. "(Tural, Selçukbiricik, Günver, Karışmaz, and Serdengecti, 2013) As early as "nine weeks"( Malik, Saxena, and Kamath, 2013) succeeding clinical surgeries, had reports of patients deaths been recorded. It has also been recorded that "one patient survived twelve years after their diagnosis. "(Ka, Gnangnon, and Diouf, 2016) The tumour has a "60% rate of metastasis and mortality in the order of 25%" (Ka, Gnangnon, and Diouf, 2016) with the highest recordings of metastases being found in "lymph nodes and lung and less commonly, bone and brain." (Ka, Gnangnon, and Diouf, 2016)

Recorded Cases
Facial localisation of a malignant chondroid syringoma
Written by Tural Selçukbiricik, Günver, Karışmaz, and Serdengecti, this report investigates the case of a slow growing bump on the face of a thirty-four-year-old woman. After undergoing an excisional biopsy, it was revealed that the nodule had developed into neurofibroma. Originally the patient had undergone excision however she sustained recurrence in under a year of the surgery. She continued to undergo excision and this led to the diagnosis of malignant chondroid syringoma. To remove the tumour, the patient first had a pathological and histopathological examination to examine the metastisation and growth pattern.

A phosphene is the perception of light without light actually entering the eye, for instance caused by pressure applied to the closed eyes.A phenomenon that could be entoptical if the eyelashes are considered to be part of the eye is seeing light diffracted through the eyelashes. The phenomenon appears as one or more light disks crossed by dark blurry lines (the shadows of the lashes), each having fringes of spectral colour. The disk shape is given by the circular aperture of the pupil. See also
