Overview

Langerhans cell histiocytosis must be differentiated from other diseases that cause bone pain, cutaneous lesions, hepatosplenomegaly, and palpable lymph nodes, such as cat-scratch disease, mastocytosis, sinus histiocytosis with massive lymphadenopathy.[1][2]

Disease Rash Characteristics Signs and Symptoms Associated Conditions Images

Pityriasis rosea[4]
  • Pink or salmon in color, which may be scaly; referred to as "herald patch"
  • Oval shape
  • Long axis oriented along the cleavage lines
  • Distributed on the trunk and proximal extremities
  • Squamous marginal collarette and a “fir-tree” or “Christmas tree” distribution on posterior trunk
  • Secondary to viral infections
  • Resolves spontaneously after 6-8 weeks

Pityriasis lichenoides chronica
  • Recurrent lesions are usually less evenly scattered than in cases of psoriasis
  • Brownish red or orange-brown in color
  • Lesions are capped by a single detachable, opaque, mica-like scale
  • Often leave hypopigmented macules

Nummular dermatitis[7]
  • Lesions commonly relapse after occasional remission or may persist for long periods
  • Pruritus

Secondary syphilis[8]
  • Round, coppery, red colored lesions on palms and soles
  • Papules with collarette of scales

Bowen’s disease[9]
  • Erythematous, small, scaly plaque, which enlarges erratically over time
  • Scale is usually yellow or white and it is easily detachable without any bleeding
  • Well-defined margins

Small plaque parapsoriasis[19]
  • Erythematous plaques with fine scaly surface
  • May present with elongated, finger-like patches
  • Symmetrical distribution on the flanks
  • Known as digitate dermatosis
  • Lesions may be asymptomatic
  • May be mildly pruritic
  • May fade or disappear after sun exposure during the summer season, but typically recur during the winter

Langerhans cell histiocytosis must be differentiated from other diseases that cause bone pain, edema, and erythema.

Disease Findings
Soft tissue infection
(Commonly cellulitis)
History of skin warmness, swelling and erythema. Bone probing is the definite way to differentiate them.[29][30]
Osteonecrosis
(Avascular necrosis of bone)
Previous history of trauma, radiation, use of steroids or biphosphonates are suggestive to differentiate osteonecrosis from ostemyelitis.[31][32]
MRI is diagnostic.[33][34]
Charcot joint Patients with Charcot joint commonly develop skin ulcerations that can in turn lead to secondary osteomyelitis.
Contrast-enhanced MRI may be diagnostically useful if it shows a sinus tract, replacement of soft tissue fat, a fluid collection, or extensive marrow abnormalities. Bone biopsy is the definitive diagnostic modality.[35]
Bone tumors May present with local pain and radiographic changes consistent with osteomyelitis.
Tumors most likely to mimic osteomyelitis are osteoid osteomas and chondroblastomas that produce small, round, radiolucent lesions on radiographs.[36]
Gout Gout presents with joint pain and swelling. Joint aspiration and crystals in synovial fluid is diagnostic for gout.[37]
SAPHO syndrome
(Synovitis, acne, pustulosis, hyperostosis, and osteitis)
SAPHO syndrome consists of a wide spectrum of neutrophilic dermatosis associated with aseptic osteoarticular lesions.
It can mimic osteomyelitis in patients who lack the characteristic findings of pustulosis and synovitis.
The diagnosis is established via clinical manifestations; bone culture is sterile in the setting of osteitis.
Sarcoidosis It involves most frequently the pulmonary parenchyma and mediastinal lymph nodes, but any organ system can be affected.
Bone involvement is often bilateral and bones commonly affected include the middle and distal phalanges (producing “sausage finger”), wrist, skull, vertebral column, and long bones.
Langerhans' cell histiocytosis The disease usually manifests in the skeleton and solitary bone lesions are encountered twice as often as multiple bone lesions.
The tumours can develop in any bone, but most commonly originate in the skull and jaw, followed by vertebral bodies, ribs, pelvis, and long bones.[38]
