Cutaneous anaplastic large cell lymphomas: a report of 9 cases from Thailand.

BACKGROUND: Anaplastic large cell lymphoma (ALCL) is one type of lymphoma, which is characterized by the proliferation of pleomorphic large atypical lymphoid cells expressing CD30 antigen. ALCL involving skin can be either primary cutaneous disease or cutaneous involvement secondary from systemic disease. Data of clinical manifestation of cutaneous ALCL in Thai patients is limited. ALCL in Thai patients may differ from other groups of patients. OBJECTIVE: To study the clinical manifestation of cutaneous ALCL in patients of Faculty of Medicine Siriraj Hospital, Thailand. MATERIAL AND METHOD: Medical records of nine patients with histopathologic diagnosis of ALCL from skin biopsy at Faculty of Medicine Siriraj Hospital were reviewed. RESULTS: Of nine patients, four patients were diagnosed as primary cutaneous ALCL, four patients as systemic ALCL with secondary skin involvement, and one patient as combined primary cutaneous ALCL and lymphomatoid papulosis. Three primary cutaneous ALCL patients had no recurrence of disease during 6-year follow-up. However all systemic ALCL patients died at one day to 1.5 years after diagnosis. CONCLUSION: Clinical manifestation and clinical course of Thai patients with anaplastic large cell lymphoma corresponded with the data from other patient population.

Pancreatic panniculitis: a cutaneous presentation as an initial clue to the diagnosis of pancreatic cancer.

BACKGROUND: Pancreatic panniculitis is a rare complication of pancreatic diseases, including pancreatic carcinoma. It is clinically manifested by erythematous subcutaneous nodules typically located on the legs which can occur before or at the onset of pancreatic disease. CASE REPORT: An 81-year-old woman presented with painful subcutaneous nodules at both shins, recurrent epigastric pain, anorexia and significant weight loss. Physical examination revealed mild pallor, palpable epigastric mass and multiple tender erythematous subcutaneous nodules discrete to both lower extremities. The skin biopsy showed lobular panniculitis with marked subcutaneous fat necrosis and ghost adipocytes compatible with pancreatic panniculitis that was an important clue for further investigations. Elevations of serum amylase and serum lipase were then noted. Computed tomography of the abdomen revealed pancreatic cancer with duodenal involvement and multiple liver metastases. CONCLUSION: Pancreatic panniculitis is associated with pancreatic cancer and represents an important clue to the diagnosis.
