Some physical signs were found, including hypopigmented macules on her back, right forearm, and right calf, ungual fibromas on her left hand, and shagreen patch
on dorsolumbar area of the back [Figure 1]d.

Major features of TSC include cutaneous lesions such as adenoma sebaceum, more than three hypomelanotic macules, shagreen patch
, and periungual fibromas; cortical tubers, subependymal nodules, retinal hamartomas, heart rhabdomyomas, renal angiomyolipomas, and lung lymphangiomyomatosis.

Based on clinical features alone, the differential diagnosis of this 13-year-old boy's soft plaque included a shagreen patch
of tuberous sclerosis, collagenoma, or a connective tissue nevus, Peyman Ghasri, M.
Recognition of specific lesions including hypomelanotic macules (>3), Shagreen patch
, forehead plaque, non-traumatic fibromas around nails and adenoma sabaceum (angiofibromas on the face) which can be identified on examination of the skin should suggest tuberous sclerosis (2, 3).

Adenoma sebaceum was the commonest (95%) cutaneous feature of tuberous sclerosis followed by ash leaf macule and shagreen patch
each seen in 90% patients followed by Koenen's tumour seen in 75% patients.
Major criteria include facial angiofibromas or forehead plaque, nontraumatic ungual fibroma, three or more hypomelanotic macules, shagreen patch
(most commonly on the torso and chest), multiple retinal nodular hamartomas, cortical tuber, subependymal nodule, subependymal giant cell astrocytoma, single or multiple cardiac rhabdomyoma, renal angiomyolipoma, and pulmonary lymphangiomyomatosis, said Dr.
