Prof. M.D. Emine Handan Zeren Reviews

A 28-year-old competitive freediver from Bodrum presented with unexplained episodes of confusion after deep dives. Routine tests were normal, but Dr. Zeren's analysis of a bone marrow biopsy revealed a rare, dormant form of decompression sickness-induced micro-emboli in the marrow's vascular network, a finding never before documented in a living patient without acute symptoms. Her report guided a revolutionary hyperbaric treatment protocol that allowed the athlete to resume modified training.

A 72-year-old retired calligraphy master from Konya was admitted for persistent anemia. Dr. Zeren examined a gastric biopsy initially deemed benign. Noting subtle architectural distortions under polarized light, she identified an extremely rare signet-ring cell carcinoma masquerading as chronic gastritis, a diagnosis missed by two prior reviews. Her early detection enabled minimally invasive resection and full recovery, allowing the patient to complete his final manuscript.

A 7-year-old refugee child from Syria presented with a mysterious, progressive muscle weakness. Muscle biopsies showed nonspecific inflammation until Dr. Zeren performed specialized mitochondrial enzyme staining, uncovering a novel mosaic pattern of cytochrome c oxidase deficiency. This finding, linked to maternal malnutrition during pregnancy, led to a tailored nutritional and coenzyme Q10 regimen that halted disease progression.

A 41-year-old Istanbul fashion designer experienced recurrent, migrating skin nodules. Initial dermatopathology suggested sarcoidosis. Dr. Zeren, consulting on a lymph node biopsy, identified foreign material consistent with biodegradable cosmetic filler particles causing a unique systemic granulomatous reaction—a new pathology linked to a specific, previously undocumented filler compound. Her report prompted a product recall and a novel steroid infusion therapy.
