Primary cutaneous anaplastic large-cell lymphoma of the eyelid: report of two cases and review of the literature

Purpose: Two new cases of primary cutaneous CD30+ anaplastic large-cell lymphoma (cALCL) of the eyelid are reported; these are analysed alongside existing cases to identify challenges relating to the diagnosis and management of such rare lesions. Material and Methods: A review of existing literature on the PubMed database is conducted using the keywords: ‘eyelid lymphoid proliferations’, ‘lymphoma of the eyelid’, and ‘primary cutaneous CD30+, ALK-anaplastic large-cell lymphoma of the eyelid’. Two new cases of cALCL are reported. Cases where patients present solely with a nodular periocular lesion are analysed for recurrence and survival rate. Results: Two new patients with a painless ulcerated nodule on the upper eyelid receive a confirmed diagnosis of cALCL after undergoing an excisional biopsy. The first, elderly patient has spontaneous remission; the second patient, with a concomitant chronic infection of hepatitis C virus (HCV), presents a more diffuse disease at the onset and requires radiotherapy. Together with 13 patients a primary cALCL identified from 11 previous studies, this constitutes a cohort of 15 patients. Of these, 10 present with an exclusively nodular lesion of the eyelid and four experience disease recurrence; no deaths from cALCL are reported. Conclusion: Differential diagnosis between primary cALCL and lymphomatoid papulosis is essential and requires careful consideration of clinical and pathologic features. Radiologic staging examination is crucial in order to exclude systemic ALCL, particularly for patients with comorbidity. Though cALCL has the pathological features of a malignant lesion, the prognosis seems favourable for patients; a relatively high percentage even experience spontaneous resolution.
