Stones, bones, groans, thrones, and psychiatric overtones: Systemic associations of sclerochoroidal calcification

Sclerochoroidal calcification (SCC) is a frequent masquerader of choroidal melanoma with important systemic associations such as hyperparathyroidism and parathyroid adenoma. Herein, we describe a case of a 67-year-old male who presented with an amelanotic choroidal lesion in the right eye (OD) and a history of kidney stones. Ultrasonography showed the lesion to be flat and calcified OD. Incidentally, a subclinical calcified plaque was also found in the fellow eye. Optical coherence tomography showed an elevated suprachoroidal mass in a table mountain configuration OD and flat configuration left eye, consistent with type 4 and type 1 SCC. The patient was referred for metabolic testing to rule out the underlying electrolyte imbalance and was found to be normal.

Conjunctival Tumors in 5002 Cases. Comparative Analysis of Benign Versus Malignant Counterparts. The 2016 James D. Allen Lecture

PURPOSE

To evaluate frequency of conjunctival tumors in all ages and compare benign vs malignant counterparts.

DESIGN

Retrospective series.

METHODS

setting: Tertiary referral center.

STUDY POPULATION

Total of 5002 patients.

OBSERVATION

Clinical features.

MAIN OUTCOME MEASURE

Differentiation of benign from malignant counterparts.

RESULTS

The tumor was benign (52%), premalignant (18%), or malignant (30%). Malignant tumors included melanoma (12%), squamous cell carcinoma (SCC) (9%), lymphoma (7%), and others. Comparison of primary acquired melanosis vs melanoma revealed melanoma with greater median patient age (54 vs 61 years, P < .0001), male sex (35% vs 49%, P < .0001), location in fornix (2% vs 6%, P = .0016) and tarsus (1% vs 4%, P = .0018), larger median basal diameter (6 vs 8 mm, P < .0001) and thickness (<1 vs 1 mm, P < .0001), and intralesional cysts (0% vs 7%, P < .0001), feeder vessels (10% vs 48%, P < .0001), intrinsic vessels (4% vs 33%, P < .0001), and hemorrhage (<1% vs 3%, P = .0001). Comparison of conjunctival intraepithelial neoplasia (CIN) vs SCC revealed SCC with greater diffuse involvement (1% vs 8%, P < .0001) and larger median basal diameter (7 vs 8 mm, P < .0001) and thickness (1 mm vs 2 mm, P < .0001). Comparison of benign reactive lymphoid hyperplasia vs lymphoma revealed lymphoma with greater median patient age (50 vs 61 years, P < .0001), fornix location (32% vs 54%, P < .0001), larger median basal diameter (10 vs 20 mm, P < .0001), and less involvement of nasal region (50% vs 23%, P < .0001).

CONCLUSION

In an ocular oncology practice, conjunctival tumors are benign (52%), premalignant (18%), or malignant (30%). Malignant tumors tend to occur in older patients and demonstrate greater basal diameter and thickness, compared with benign counterparts.
