[Re-re-relapse of a MALT lymphoma of the conjunctiva]

The MALT lymphoma (mucosa-associated lymphoid-like tissue lymphomas) is a rare entity and belongs to the low-grade non-Hodgkin (NHL) lymphomas. In 8 % of cases it arises in the conjunctiva. In some cases a MALT lymphoma of the conjunctiva is misdiagnosed as chronic conjunctivitis. Mostly a MALT lymphoma of the conjunctiva can be cured by radiation and has a good prognosis.

A 61-year-old female presented to our hospital because of alteration of the conjunctiva and worsening of her general condition. Symptoms were fatigue, lassitude, night sweat, loss of appetite and gastrointestinal problems. The medical history revealed treatment for a MALT lymphoma 4 years previously and a relapse 3 years previously. Both were resected totally. Staging at those times gave no hint for metastases. The ophthalmological examination showed an adherent prominence with conjunctival injection of the right eye at 10 - 11 o'clock. It corresponded to the localisation of the primary tumour in 2002 and the relapse in 2003. Slit lamp and fundoscopic examinations only revealed a cataracta incipiens.

To confirm the diagnosis a biopsy was done. The histological examination demonstrated a relapse of the MALT lymphoma. Staging gave no hint for metastases. The patient was referred to the oncological unit for chemotherapy (R-CHOP regime).

This case shows that a relapse of the MALT lymphoma may arise although the previous tumour and its relapse were resected totally. In patients with tumours in their medical history suffering from unspecific discomfort, a biopsy should may be be considered despite the lack of apparent macroscopic findings.
