Proper diagnosis of scleroderma is often long and difficult, since it is a such a rare disease, and one which few doctors or patients are well-versed in.

Linear scleroderma is a line of thickened skin which can affect the bones and muscles underneath it, thus limiting the motion of the affected joints and muscles. It most often occurs in the arms, legs, or forehead, and may occur in more than one area.

It is most likely to be on just one side of the body. Linear scleroderma generally appears in young children, and is characterized by the failure of one arm or leg to grow as rapidly as its counterpart. (Also see Types of Scleroderma)

Autoimmune Disorder

Case Report: Facial solitary morphea profunda presenting with painful trigeminal neuropathy. This is the first case of solitary morphea profunda associated with painful trigeminal neuropathy. PubMed, Cephalalgia. (Also see Trigeminal Neuralgia)

Systemic sclerosis (SSc) complicated with localized scleroderma-like (Lsc) lesions induced by Köbner phenomenon. The epidermis of SSc patients with LSc-like lesions seems to possess an inflammatory phenotype, leading to the activation of mast cells in the dermis of mechanically stressed skin. PubMed, J Dermatol Sci, 2018 Mar;89(3):282-289. (Also see Localized Scleroderma)

Blaschko's Lines

Linear morphoea follows Blaschko's lines. Our data indicate that linear morphoea follows the lines of Blaschko. We hypothesize that in patients with linear morphoea susceptible cells are present in a mosaic state and that exposure to some trigger factor may result in the development of this condition. PubMed, Br J Dermatol. (Also see Morphea)

Diagnosis of Linear Scleroderma

Diagnosis of Linear Scleroderma is usually done by clinical examination. It is often confirmed by skin biopsy. Skin biopsies are usually a very tiny sample of tissue and the procedure is often very quick, easy and with minimal discomfort. Ultrasound has also been found to be useful for the diagnosis of Localized Scleroderma (such as linear). ISN.

Sclerodermic Linear Lupus Panniculitis

Linear lupus panniculitis of the scalp presenting as alopecia along Blaschko's lines: a distinct variant of lupus panniculitis in East Asians? We propose linear lupus panniculitis of the scalp to be a distinct variant of lupus panniculitis and should be included in the differential diagnosis for focal or linear alopecia, especially in East Asians. J Dermatol.

Case Reports: Sclerodermic linear lupus panniculitis. Lupus erythematosus panniculitis is a rare disease characterized by deep subcutaneous nodules, most commonly localized on the upper limbs and face. We present here the clinical characteristics, course and laboratory findings of 2 patients having linear lupus erythematosus panniculitis with localized scleroderma-like changes. PubMed, Dermatology.

Linear Patient and Caregiver Stories

AJ Miller: Linear Scleroderma I have had Linear Scleroderma since 1968, when I was 7 years old. I have never met anyone else with it…

Alicia: Linear Scleroderma My doctor said the people who are looking at me and seeing the scars are the ones who need healing, and that I should pray for them…

Alicia B: Localized Morphea with possible Parry Romberg Syndrome The doctor kept saying something had eaten away at all the fatty tissue and the muscles which left it just skin, blood, bone, and nerve so when you look at it, it looks like I have dirt on my face and a gaping hole to go with it…
