A 25-year-old female presents with a painful blind eye.
The eye is enucleated.
The iris is rubeotic with secondary angle closure.
There is an anterior polar cataract.
There is a serous retinal detachment. Closure inspection of the retina shows several lesions, with their bases on the optic fibre layer.
Figure 1 is a low power of one of these retinal lesions.
Figure 2-higher power to show cytology of the retinal lesion.

1. What is the diagnosis?
2. What are the non-ocular lesions that may be present in this case?
1. Non-calcified retinal astrocytic hamartoma. The older the patient, the more likely calcification is present. This patient had tuberous sclerosis complex.
2. Tuberous sclerosis complex is caused by germline mutations in TSC1 or TSC2.
Some of the major manifestations are as follows:
CNS: Cortical tuber, sub-ependymal nodule, white matter hamartoma, sub-ependymal giant cell astrocytoma.
Skin: Adenoma sebaceum, hypomelanotic macule, shagreen patch, forehead plaque, peri- and subungal fibroma.
Eyes: Retinal astrocytic hamartoma, retinal giant cell astrocytoma, hamartomas of the iris and ciliary epithelium.
Heart: Cardiac rhabdomyoma
GIT: Microhamartomatous rectal polyp and liver hamartoma.
