   Introduction Top


Malignant melanoma of the eyelid is a rare condition. They are rare in children but quite common in adult age groups. Lesions are typically single, unilocular without gender preference [1] .Usually these tumors arise from the choroid layer of the eye. Rarely are they known to occur in the eyelid. These have no known diagnostic features when they arise from the eyelid. However they must be included in the differential diagnosis of eyelid masses. Usually these are quite aggressive lesions; however in the event they occur in the eyelid their course is unpredictable. We present a similar case that occurred in our institution.


   Case history Top


A 40 years old male presented with a large lobulated lesion arising from the right eyelid involving the upper and lower eyelid. No ulceration or signs of inflammation present.

Past history of similar such lesion existed, which involved the upper eyelid. The lesion was excised. No past operative notes or histopathological reports were available. Present lesion had existed for more than 6 months, patient had ignored the lesion which had grow in sign to such a extent that at present it was seen to compromise vision with restricted mobility of right eyelids [Figure - 1].

Imaging features:

Ultrasound Findings:


   B Mode ultrasound (B scan orbit): Top


Ultrasound examination was done with GE Logiq 400 TM ultrasound scanner with a high frequency linear probe of 9 to 11 MHz. Ultrasound revealed a hypo echoic lobulated mass seen to involve the upper and lower eyelid. No calcification or necrotic areas were noted within the lesion. The globe appeared normal in size. It was displaced posteriorly and laterally without evidence of any intraglobe pathology. The anterior chamber was shallow. Dynamic scan mode was not possible due to restriction of globe mobility. [Figure - 2].


   On color Doppler mode Top


The lesion revealed mild to moderate vascularity. The spectral pattern demonstrated low velocity arterial flow waveforms and interspersed venous flow [Figure - 3].


   CT scan of orbit Top


The lesion showed heterogeneous enhancement on contrast enhancement with poor plane of separation between the globe and the lesion. The lesion was predominantly preseptal with possibility of early intraconal extension along the inferonasal portion of the orbit. Optic nerve was normal. No bone erosion or destruction noted. [Figure - 4][Figure - 5].

The patient was operated and there was exenterating of the orbit. Operative findings were consistent with imaging. The specimen was sent for histopathological examination.[Figure - 6].


   Discussion Top


Orbital melanomas are mostly limited to the choroids and arise from preexisting nevi [2]. However they can occur anywhere in the globe. Large malignant melanomas of the eyelid are rare entities and most of the time they arise de novo. The various imaging modality can be used to assess the various aspects of eye in relation to the pathology and prove to be complementary to each other.

B scan facilitated the confirmation of intraglobe pathology and associated abnormalities in relation to movement of the globe. Color Doppler assisted in knowing the vascularity of the tumor. CT scan facilitated in providing a better view of the spread/extension into the extra orbital region.
