“…At dermoscopy, pigmented dots around the hair follicles or the presence of asymmetric pigmented hair follicular openings are the earliest signs of LM (Figure 2), which suggests the follicular origin of LM. 15 The morphologic hallmark of early SSM in situ is a pigment network pattern, which corresponds histopathologically to an increased number of melanocytes at the basal layer (Figure 3) and underscores an epidermal origin for this melanoma subtype. 16 The study by Segura et al 1 in this issue of the Archives is of particular interest because it lends support to our hypothesis by showing important differences between NM and SSM with secondary invasive nodular components using RCM.…”

EGURA ET AL 1 DESCRIBE MORPHOLOGIC FEAtures of melanomas with a nodular component using in vivo reflectance-mode confocal microscopy (RCM) and correlate these RCM findings with histopathologic findings. The most striking observation made by the investigators is the remarkable difference in epidermal involvement between nodular melanoma (NM) and superficial spreading melanoma (SSM) with a nodular component. At RCM, SSMs frequently showed epidermal disarrangement and pagetoid infiltration, whereas NMs exhibited a preserved epidermal pattern and few paget-

“…[11][12][13][14][15] More recently, several research groups have reported specific criteria for diagnosing melanoma in the context of various anatomic locations such as the acral and facial areas. 16,17 To name but a few examples, it was established that rhomboidal structures and a parallel-ridge pattern are the most important dermoscopic criteria for diagnosing lentigo maligna of the face and acral melanoma in situ, respectively. By keeping in mind these specific features, the dermatologist may diagnose melanoma in these particular locations with increased confidence.…”

“…A pseudonetwork was defined as a blue-gray to brown diffuse pigmentation formed by the confluence of annular-granular structures surrounding the follicular openings [2]. The typical pseudonetwork that results from the anatomical architecture of the facial skin owing to the flattened rete ridges with pigmentation that avoids the hair follicles is a diagnostic clue for melanocytic lesions and solar lentigo in the facial area, and can exclude BCC in general.…”

Atypical Pseudonetworks in Pigmented Facial Macules: A Report of Two Cases

We report two rare cases of a black facial macule showing atypical pseudonetwork on dermoscopy. Case 1 was a reticulated type of seborrheic keratosis and case 2 was a superficial Basal Cell Carcinoma (BCC). In general, pseudonetwork is seen in benign or malignant melanocytic lesions. Specifically, an atypical pseudonetwork is known as a hallmark of lentigo maligna and lentigo maligna melanoma. An atypical pseudonetwork is composed of four elements: asymmetrical pigmented follicular openings, rhomboidal structures, annular granular structures, and a gray pseudonetwork. We found no case report of a reticulated-type seborrheic keratosis showing asymmetric pigmented follicular openings with a dark brown rim, as was seen in our case. Furthermore, reticular lines including a pigment network and pseudonetwork are important features, excluding pigmented BCC, and only one case of superficial BCC with an atypical pseudonetwork has been reported. In Case 2, pseudonetwork made of blue-gray network-like pigmentation on pink whitish structureless areas could be seen. It is important to know the diagnostic pitfalls of non-melanocytic pseudonetwork on dermoscopy, although it has useful features for diagnosis of facial pigmented lesions.
