RESUMEN
We present a case of a relapse of HL revealed by a skin involvement. A biopsy of the skin lesion showed infiltration by a mixed cellularity and Reed-Sternberg cells. The immunoreactivity was positive for CD30 and CD15. The patient was undergoing ICE protocol with good improvement after three cycles.
RESUMEN
Pneumoblastoma is a rare primary childhood tumor. We report the observation of an infant aged 2 years and 8 months who presented with dry cough and dyspnea. The physical examination found mixed pleural effusion syndrome on the right. The chest X-ray revealed a right pneumothorax. Biology has shown leukocytosis at 16,000/mm3. The CT scan revealed parenchymal air cystic lesions affecting the outer segment of the middle lobe mimicking a pulmonary malformation. Thoracic drainage brought back 100 ml of the fluid. Two months later, when a pyopneumothorax appeared, a medium lobectomy was performed. Pathological study specimen showed a high-grade type II pneumoblastoma The extension assessment identified a secondary hepatic location. Chemotherapy has been indicated. This observation illustrates the diagnosis challenge of pneumoblastoma in children.
RESUMEN
A 37-year-old woman with no remarkable medical or family history presented with papules and vesicles on an erythematous background involving the neck, sacrum, and folds (postauricular, axillary, inguinal, and under the breasts) (Figure 1). During the previous year, she was treated with local and systemic antifungals without improvement. Her history included a secondary amenorrhea, polydipsia, and polyuria (6 L/d) that started 2 years prior. Physical examination revealed chronic bilateral purulent otorrhea with thick eardrums. Histologic examination of skin biopsy revealed a highly suggestive appearance of multisystem Langerhans cell histiocytosis (LCH) with immunohistochemistry (anti-PS100 and anti-CD1a), which were positive (Figure 2A and 2B). Pituitary magnetic resonance imaging showed a thickening of the pituitary stalk in relation to a location histiocytic (Figure 3). Bone gaps were objectified on two radiographic tibial diaphyseal. Results from computed tomography (CT) scan showed a magma coelio mesenteric, axillary, and inguinal lymph nodes.
