Lung carcinoma with congenital plantar keratoderma as a variant of Clarke-Howel-Evans syndrome.
A 32-year-old man was admitted to the Magdeburg University Hospital with icterus and for further diagnosis of suspected hepatitis. He also complained of generalized pruritus, abdominal pain, nausea, and diarrhea. The patient's history revealed the excision of a lymph node metastasis of the left groin showing pleomorphic macrocellular infiltrates, 2 months previously. The patient presented to our department with prominent hyperkeratosis of both feet, which had been present since early youth. The family history was negative. Both soles showed very thick, white and blackish hyperkeratosis with predominance of the heels and the forefeet (Fig. 1). The naturally occurring wrinkles of the skin of the toes were flattened. The palms were not affected, and neither was the oral mucosa. Further investigations revealed icterus of the sclera and multiple, firm tumors, which were located in the deep subcutaneous tissue, on the left hip, thigh, and buttock. From thorough clinical, laboratory and staging investigations, a non-small-cell bronchogenic carcinoma, with metastases of the liver, kidneys, adrenal glands, and several skin sites, was diagnosed. A skin biopsy specimen of the foot showed substantial acanthosis of the epidermis with hypergranulosis and excessive orthohyperkeratosis. The corneocytes were enlarged and arranged in a tile-like pattern (Fig. 2). The dermis was free of inflammatory infiltrates and human papillomavirus infection was ruled out by immunohistochemistry. Polychemotherapy was immediately started with 5-fluorouracil, mitomycin, and cisplatin, which was well tolerated. When the patient was admitted for the second cycle, however, his general health had worsened markedly. He complained of abdominal pain, severe weight loss, and nausea. Generalized metastases showed substantial progression. Chemotherapy could not be continued because of a Karnowsky index below 20%. The patient died 2 weeks later.
