  Abstract 


A 45-year-old female presented with a history of pedunculated, soft, nodule on the right leg in popliteal region for 5 years. The lesion started as a small nodule and increased in size for 2 years and remained unchanged thereafter. The histological examination confirmed ectopic mature adipose tissue within dermis that supported the clinical diagnosis of nevus lipomatosus. This case report is of a solitary form of nevus lipomatosis cutaneous superficialis or pedunculated lipofibroma.

Keywords: Adipocytes, ectopic adipose tissue, nevus lipomatosus, papules and cutaneous neoplasm

  Introduction Top


Nevus lipomatosis cutaneous superficialis (NLCS) is a rare idiopathic hamartomatous anomaly, the classic Hoffman–Zurhelle type or multiple form and the pedunculated solitary form. Usually, it presents with asymptomatic grouped, soft, skin-colored to yellow papules and nodules within the first three decades of life. There is neither familial tendency nor sex predilection. Histology is characteristic with ectopic mature adipose tissue within dermis.[1],[2]


  Case Report Top


A 45-year-old female presented with a 5-year history of nodule on her right leg.

The lesion started as a small, single nodule and increased in size for 2 years and remained unchanged thereafter. The lesion caused no symptoms except for unsightly appearance. There was no family history of similar lesions. Physical examination revealed single soft, skin-colored nodule 1.5 cm × 1 cm on the right leg. Systemic examination revealed no abnormality. All routine laboratory investigations were within normal limits. The suggested clinical differential diagnoses were skin tag, dermolipoma, and wart. The nodule was excised. Received single skin covered tissue bit in formalin measuring 1.5 cm × 1.0 cm × 0.8 cm, cut section was gray yellow. Histopathological examination revealed epidermis with hyperkeratosis. Dermis shows mature adipose tissue [Figure 1] and [Figure 2]. These findings supported the diagnosis of nevus lipomatosus.

  Discussion Top


NLCS is an uncommon idiopathic hamartomatous anomaly, presented with soft, flattened papules or nodules that have smooth or wrinkled surfaces and are skin colored or pale yellow. Mostly the lesions are linearly distributed or may overlap on to the adjacent skin. Histology shows ectopically situated mature adipocytes within the dermis.[1] Clinically, there are two types. The classic (or multiple) type [2] usually presents within the first three decades of life with clusters of soft, cribriform, and peau d'orange appearance, located most commonly on the lower trunk, especially on the back, buttocks, or hips and on the upper posterior thighs.[1],[3],[4],[5]

Rare involvement of the face [6] or scalp [7] has been reported. They are generally present at birth, but they may first appear during childhood or adolescence.[4],[8]

They are almost invariably asymptomatic although occasionally ulceration may occur.[9] The solitary form of NLCS usually appears during the third to sixth decades of life as a single papule or nodule without a favored location.[3],[10],[11] There is no evidence of a familial tendency or sex predilection in either clinical type.[3] There are reports of coexisting café-au-lait macules, leukodermic spots, overlying hypertrichosis, and comedo-like alteration.[3],[12]

Histopathology

Groups and strands of fat cells are found embedded among the collagen bundles of dermis often in papillary dermis. Proportion of fat tissue varies from 10% to more than 50%. The fat cells may all be mature, but in some instances and an occasional small, incompletely lipidized cell may be observed. NLCS contains fat cells but no skin appendages in the dermis.[13]

Pathogenesis

It represents a nevoid anomaly. The ectopic fat cells in the dermis are derived from perivascular mesenchymal tissue.[13] Other theory for etiopathogenesis is adipose tissue metaplasia during the degenerative changes in dermal connective tissue, 2p24 deletion has also been noted.[14]

A recent report described a giant NLCS with multiple folliculosebaceous cystic hamartomas and dermoid cysts.[15] A case of NLCS with localized scleroderma-like appearance has been reported.[16] The differential diagnosis before biopsy may include old nevocellular nevi, sebaceous nevus, neurofibromas, connective tissue nevi, epidermal nevi, the dermal variant of spindle cell lipomas, acrochordones, focal dermal hypoplasia, lipoblastomatosis, and Michelin tire baby syndrome.[3] Sebaceous nevus contains skin appendages in contrast to NLCS.

The dermal variant of spindle cell lipoma contains more spindle-shaped cells as well as a fibromucinous stroma. In focal dermal hypoplasia, fat cells present in dermis, often in proximity to epidermis but have concomitant extreme attenuation of collagen.[3]

Focal dermal hypoplasia is also associated with several ectodermal and mesodermal deformities include syndactyly, hypoplasia of hair, nails, and teeth. Similar dermal collections of the adipose tissue may occur as a component of long-standing intradermal melanocytic nevi and in pedunculated lipofi broma but long-standing intradermal melanocytic nevi associated with nevus cell nests and represent an involutory phenomenon.[17] To date, there have been no reports of malignant degeneration and recurrences are extremely rare, so treatment is not medically necessary.[3]

For cosmetic purposes, surgical excision is the best choice.[3],[18]

No significant complications observed in majority of cases. In some cases, foul-smelling discharge can occur, due to ulceration. In some rare cases, the tumor may recur after surgical excision. At present, the term “pedunculated lipofibroma” is used to denote solitary forms of NLCS.[19]

Another recent report described a rare case of congenital classical NLCS presented as cerebriform lesions with centrally located comedo-like plugs.[20]

Epidermal changes such as mild to moderate acanthosis, basket weave hyperkeratosis, obliteration of rete pegs, increased basal pigmentation, and focal elongation of rete pegs have been reported.[21]

In our case, the lesion was completely excised and no recurrence was observed.


  Conclusion Top


Solitary form of NLCS is rare compared to classical multiple form; hence, here, we report a rare case of pedunculated lipofibroma.

Physicians should be aware of this rare condition because early recognition enables more conservative resection of the tumor and less invasive reconstruction of the defect. Rare association with other malignancies should be remembered.
