REVIEW
Pembegül Güneş, Fatih Göktay
Melanocytic lesions of the nail unit are traditionally classified as follows: melanocytic activation, lentigo, nevi, and melanoma. Undoubtedly, melanoma is the most important malignant tumor of the nail unit. Differentiating nail unit melanoma from other melanocytic lesions is often difficult both clinically and histopathologically. This article will first describe the histology of the nail unit, followed by a brief summary of clinical and histopathological features as well as differential diagnosis of melanocytic lesions of the nail unit...

Shadow cells are characterized by an eosinophilic cytoplasm and a ghost-like nuclear contour; the cell shape is preserved, in spite of nuclear disappearance. Shadow cell nests (SCNs) are frequently observed in pilomatricoma (PMX), where the transitional cells immediately adjacent to SCNs often have a crescent-shaped nucleus showing fragmentation similar to that of apoptotic bodies. They show nuclear accumulation of beta-catenin and DNA double strand breaks (as revealed by in situ 3'-tailing reaction or immunohistochemistry for single-stranded DNA [ssDNA]), while they are negative for cleaved caspase-3 or cleaved lamin A, suggesting that shadow cell differentiation (SCD) is a caspase-independent programmed cell death...

REVIEW
Gürkan Kaya, Jean-Hilaire Saurat
Cutaneous cysts have been classified by dermatopathologists in many different ways. Here, we propose a novel classification of cutaneous adnexal cysts according to their origin in the folliculosebaceous unit and the sweat glands. By examining the lining of the cystic structure, its origin can be easily identified. Epidermal cysts have an epithelial wall containing a granular layer with lamellar keratinization, indicating an infundibular origin. Tricholemmal cysts have an undulating epithelial wall with no granular layer and a compact keratinization, showing an isthmic origin...

Glomus tumors are soft tissue neoplasms, which are most frequently encountered in the nail unit and generally straightforward to diagnose by histopathology. The typical clinical presentation is that of a circular violaceous or erythematous lesion within the nail bed. However, there are rare variants of glomus tumors which may pose diagnostic challenges because of the presence of unusual histologic features. Herein we report such a glomus tumor that demonstrates the rare combination of both myxoid and symplastic change...

Sign of Leser-Trélat is a rare paraneoplastic cutaneous manifestation, characterized by the sudden appearance and rapid increase in size and number of seborrheic keratoses, accompanied by pruritus. Edmund Leser and Ulysse Trélat described this sign in 1890. Since their first description, their conclusions have been considered controversial and some authors assert the absence of a causal link. It seems to be frequently associated with solid tumors and in particular gastrointestinal cancer. Here, we describe a new case associated with a cutaneous T-cell lymphoma and a partial response to extracorporeal photopheresis...

Cutaneous squamous cell carcinoma (SCC) exhibiting microcystic adnexal carcinoma-like differentiation is an extremely rare tumor that shows both squamous and ductal differentiation. This tumor is often misdiagnosed clinically and histologically and is confused with other malignant and benign cutaneous neoplasms. It usually occurs in middle-aged to older adults. Here, we report a case of SCC with microcystic adnexal carcinoma-like differentiation on the left chin of a 71-year-old male. The histopathological examination revealed a nodular tumor infiltrating the dermis, subcutaneous fat, and striated muscle tissue, consisting of both prominent atypical squamous differentiation and foci of duct-like structures...

Background: Steatocystoma multiplex is a benign skin disorder originating from the sebaceous and nevoid ducts. Commonly classified under hamartomas, they are distributed over the trunk, neck, axillae, and groin. Methods: A 28-year-old male patient complained of multiple, asymptomatic skin-colored nodules over the face of 10-year duration. Clinical examination confirmed the historic findings of nontender, polysized, flesh-colored papules and nodules over the said distribution...

Patients who present with papular rashes have a wide differential diagnosis particularly in the setting of immune compromise. A 30-year-old male diagnosed with HIV since 2009, never on antiretroviral therapy, with a nadir CD4 count of 333 cells/mm3 and a current viral load of 44,300 copies/mL, presented with a diffuse monomorphic papular eruption that began on his trunk and extremities and subsequently spread to the penis and scrotum, sparing the distal acral sites. A thorough infectious workup revealed a positive rapid plasma reagin (RPR) and varicella IgM and IgG antibodies...

Churg-Strauss syndrome or eosinophilic granulomatosis with polyangiitis is a systemic vasculitis affecting the small and medium-sized vasculature. It is commonly associated with asthma and eosinophilia. Most patients are diagnosed at around the age of 40. We report a case of biopsy-confirmed Churg-Strauss syndrome in a 92-year-old male with a history of eosinophilic asthma and peripheral eosinophilia who was later diagnosed with Churg-Strauss syndrome.

REVIEW
Gerardo Ferrara, Antonietta Partenzi, Alessandra Filosa
Several controversies are still ongoing about sentinel node biopsy in melanoma. It is basically a staging procedure for melanoma > 0.75 mm in thickness or for thinner melanoma in the presence of ulceration, high mitotic rate, and/or lymphovascular invasion. Complete lymph node dissection after a positive sentinel node can also allow a better locoregional disease control but seems not to prevent the development of distant metastases. The use of sentinel node biopsy in atypical Spitz tumors should be discouraged because of their peculiar biological properties...

Cutaneous mucinoses are a group of conditions characterized by increased amounts of acid mucin in the dermis. They can be generalized or localized and occur isolated or in the setting of systemic diseases. Obesity-associated lymphedematous mucinosis is a distinct variant of mucinosis occurring in obese patients without any thyroid dysfunction. So far, only few cases of this rare condition have been reported in the English literature. Here, we describe two new cases and discuss some histological differences with the pretibial myxedema...

Epidermolysis bullosa acquisita (EBA) is a rare mucocutaneous blistering disorder with typical onset in adulthood. Diagnosis and management can be difficult owing to the variability in presentation and clinical manifestation. In this case, we explore a case of EBA as well as provide a general overview of the condition and its variants.

Angelo Cassisa
The term "neutrophilic dermatoses" includes a rare inflammatory pattern characterized by neutrophil-rich cutaneous infiltrate. Both innate and adaptive immune pathways may be involved in neutrophil recruitment. Occasionally, neutrophilic dermatoses may occur in association with autoimmune thyroiditis. Pathogenetic aspects of this autoimmune disorder may elucidate their possible connection. Two exemplificative cases are taken as a pretext for a short review of this topic.
