Abstract:Extensive evaluation of the condition of a 9-year-old girl with a previously undescribed proliferative histocytic syndrome showed normal serum and tissue lipid values, which rule out the known lipid storage diseases. Clinically and histologically the case is inconsistent with any of the recognized xanthomatoses or histiocytic abnormalities.
“…The latter may also occur sporadically [1,12]. In our patients, the nodules were the predominant clinical feature.…”

“…Taunton and colleagues also described conjunctival involvement as seen in our patient 2. A unique fi nding in patient 2 was ocular involvement with epibulbar infi ltrates, which has only been reported once thus far [1]. An association with retinitis pigmentosa, without an evident causal relationship has been reported in one patient [24].…”

“…There have been no reports of involvement of internal organs. The disease can also affect children [1,13,14]. Except for one patient with an association with leukemia [15], there seems to be no association with malignancies or chronic infl ammatory diseases.…”

“…Only one other patient had involvement of the palms and soles [22]. Mucosal involvement has been occasionally reported, including the publication by Taunton and colleagues [1], who were the fi rst to describe this disease. In one patient, extensive laryngeal involvement led to respiratory diffi culty and resulted in laser removal of the nodular infi ltrates, which was also necessary in patient 1 [23].…”

“…It is characterized by the clinical appearance of yellow papules and larger nodules on the head, trunk, and extremities; mucous membrane involvement can occur on occasion as well [1]. There have been reports of severe and disfi guring forms of disease, but not of involvement of internal organs or systemic complications.…”
SummaryProgressive nodular histiocytosis (PNH) represents a very rare type of non-Langerhans cell histiocytosis (NLCH). It can be distinguished from other types by the occurrence of yellow to red-brown papules and nodules measuring a few centimeters in size. Histologically the nodules represent spindle-cell xanthogranulomas. We report on two new cases of PNH with novel clinical symptoms. In the first case, the patient had microcytic anemia due to massive iron deposition in the nodules and a progressively worsening limp due to involvement of the soles. The complex therapeutic challenge was effectively managed by successive surgical ablation of all visible lesions. The second patient had epibulbar infiltrates. The clinical variability of PNH leads to considerable overlap with other forms of NLCH.

A man in his 70s with a 4-year history of stage IV chronic lymphocytic leukemia (CLL) presented with a 12-month history of an asymptomatic skin eruption. His CLL had been in remission for 2 years after treatment with fludarabine and rituximab before he relapsed and underwent 6 cycles of RCHOP treatment (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone). During his CLL relapse, he developed cutaneous nodules on his face that then spread diffusely. The patient denied fevers, arthralgias, bone pain, polydipsia, or polyuria. Physical examination revealed multiple 0.5-to 1.5-cm reddish-brown firm papules and nodules on his cheeks, torso, buttocks, and extensor surfaces of his extremities (Figure, A), sparing his eyelids, palms, soles, and mucous membranes. Triglyceride levels were mildly elevated at 211 mg/dL; otherwise the patient's lipid levels were normal (to convert triglycerides to millimoles per liter, multiply by 0.0113). A biopsy of a representative papule on the thigh was performed, and a routine hematoxylin-eosinstained section (Figure, B) and CD68 immunohistochemically stained section (Figure, C) are shown. Findings of CD1a and S100 stainings were negative.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
