Multiple schwannomas can occur in patients with neuroﬁbromatosis, but solitary schwannoma is usually unassociated with that entity. Schwannoma is known to arise in the orbit (1–8); occasionally, it occurs in the uveal tract, conjunctiva, caruncle, or eyelid. Clinical Features Clinically, schwannoma of the eyelid appears as a ﬁrm subcu- taneous mass that can simulate a chalazion. Pathology Histopathologically, schwannoma is an encapsulated lesion that is composed of closely compact spindle cells (Antoni A pattern) and larger, more round clear cells (Antoni B pattern). Management Management is complete excision; incomplete removal is asso- ciated with eventual recurrence and more aggressive behavior (3–5). This lesion was also previously managed elsewhere by cessful removal of the lesion. Regional lymph noted dissection, irradiation, and from specialized neuroendocrine receptor cells of the skin and chemotherapy are believed to improve the prognosis mucous membranes, known as Merkel cells. Radiotherapy (50 Gy) has been reported to achieve appear to mediate touch sensation and are thought to be complete tumor control after 24 months (20). It is an aggressive malignant Concerning prognosis, Merkel cell carcinoma often tumor that can exhibit local recurrence and distant metasta- exhibits early regional lymph node metastasis and distant sis. As mentioned, the 5-year survival for all Merkel to develop regional or distant metastasis (4). The speciﬁc prognosis for eye- cinoma can occur on the trunk, extremities, and face. Clinical Features Approximately 10% of all cases of Merkel cell carcinomas affect the eyelid and periocular skin (4). Of those, the upper eyelid is involved in 64%, lower eyelid in 13%, canthi in 11%, and unspeciﬁed eyelid sites in 13% of cases (1). Clinically, eyelid Merkel cell carcinoma usually occurs as a painless pro- gressive, red or violaceous, reddish-blue nodule near the eye- lid margin. It has a predilection for elderly women but has been recognized in a 22-year-old woman (18). Like seba- ceous carcinoma, Merkel cell carcinoma can masquerade as a chalazion, resulting in serious delay in diagnosis (9,15).

Sodium depletion is diagnosed largely If there is no history of fuid loss, on clinical grounds, whereas in patients water retention is likely. Many patients with suspected water retention, history Severity will not give a history of water retention and examination may be unremarkable. It may be low or high in The serum sodium concentration If they are present in the recumbent sodium depletion depending on whether itself gives some indication of dangerous state, severe life-threatening sodium the pathological loss is from gut or or life-threatening hyponatraemia.
