Bezoars are the accumulation of undigested foreign bodies or food
material in the gastrointestinal tract that form a conglomeration (1),
(2). They may be composed of hair (trichobezoars), vegetable matter
(phytobezoars), milk curd (lactobezoars), and, very rarely, stones
(lithobezoars) (3). Lithobezoars are very rare in childhood and are most
often seen in neglected and emotionally disturbed children (4), (5).
This study aimed to present the clinical features of a 15-year-old male
patient with a history of pica and iron deficiency that did not respond
to oral iron therapy, and to highlight the diagnostic and management
challenges of childhood lithobezoars.
A 15-year-old boy was referred to our department with iron deficiency anemia. He had a history of constipation, recurrent abdominal pain, and fatigue for 5 years. The boy was a neglected child of a family with low socioeconomic status. He was working as a carpenter in wood industry. He appeared pale and had sensitivity in both lower quadrants of the abdomen. Laboratory findings were as follows: hemoglobin: 7.5 g [dL.sup.-1], MCV: 54 fL; serum iron: 8 [micro]g [l.sup.-1]; iron binding capacity: 395 [micro]g [l.sup.-1]. Peripheral blood examination showed hypochromic microcytic anemia, anisocytosis, and target cells. Plain abdominal X-ray showed numerous opacities scattered within the small intestine, ileocecal valve, and descending colon (Figure 1). Detailed anamnesis showed that he had been eating pieces of charcoal for 8 years. Because the patient did not satisfactorily respond to long-term oral iron supplementation, he was referred to admit to a hematologist by his family practitioner. When he submitted us in Training and Research Hospital, parental iron therapy was applied because of the persistent anemia. He was referred to the department of psychiatry because of behavioral problems.

Bezoars result from pica, an appetite for unpalatable or non-nutritive objects. The etiology of pica is unknown; it may be a consequence of parental neglect and deprivation early in life. It is more commonly observed in impoverished, emotionally disturbed children of low socioeconomic status that often have a problematic home environment. A history of pica invariably precedes the formation of a lithobezoar (6). The presented case also had pica.
Bezoar patients may present with a history of ingestion of sand, constipation, and recurrent episodes of abdominal pain that may result in significantly painful defecation, which is an important indication for the diagnosis of lithobezoars. Abdominal palpation and rectal examination provide important diagnostic evidence of colonic lithobezoars. Palpation of a prickly mass on rectal examination is known as the colonic crunch sign and can be observed in cases of sunflower seed bezoars and lithobezoars. Plain abdominal X-ray is especially important in the diagnosis of this type of colonic intraluminal mass. The presence of numerous radiopaque masses in the lower abdomen or the rectosigmoid junction, referred to as corn on the cob, is pathognomonic for lithobezoars (5), (7).
In the presented case a history of ingestion of charcoal, iron deficiency anemia, constipation, and recurrent episodes of abdominal pain contributed significantly to the diagnosis. As in all cases of bezoars, psychiatric evaluation is essential to prevent recurrence. Early diagnosis and intervention are necessary in suspected cases of lithobezoars to avoid intestinal obstruction.
